Starting a linear motion automation project can be overwhelming when you're faced with dozens of actuator models, control options, voltage requirements, and mounting configurations. Whether you're building a motorized TV lift, automating a hatch, creating adjustable furniture, or prototyping an industrial mechanism, you need more than just a linear actuator—you need a complete system that works together seamlessly.
At FIRGELLI Automations, we frequently receive requests for comprehensive linear actuator kits that include everything needed to get a project operational. Rather than sourcing components separately and hoping they're compatible, a properly configured kit eliminates guesswork and gets you up and running faster. This guide breaks down what components are essential in a complete linear actuator system and presents four distinct kit configurations to match different project requirements and complexity levels.
Understanding what's included in each kit type—and why—will help you select the right starting point for your application, whether you need basic manual control or advanced wireless operation with position customization capabilities.
Essential Components of a Linear Actuator Kit
A functional linear actuator system requires four fundamental component categories. Each element plays a critical role in creating a reliable, controllable linear motion system:
The Linear Actuator
The actuator itself is the mechanical muscle of your system, converting electrical energy into precise linear motion. Choosing the right actuator involves several specifications: stroke length (how far it extends), force capacity (how much weight it can push or pull), speed (how fast it moves), and voltage (typically 12V or 24V DC). FIRGELLI offers multiple linear actuator series, from compact micro linear actuators for light-duty applications to robust industrial actuators capable of moving heavy loads.
Mounting Hardware
Secure mounting is non-negotiable for safe, reliable operation. Mounting brackets provide the mechanical interface between your actuator and the structure it's moving. Most applications require brackets at both ends—one for the stationary mounting point and another for the moving element. Bracket selection depends on your actuator model, mounting orientation, and load characteristics. Poor mounting practices are among the most common causes of premature actuator failure.
Control System
Linear actuators require polarity-reversing control to extend and retract. The simplest option is a manual rocker switch that reverses current direction when toggled. More advanced applications benefit from wireless remote control systems or programmable controllers like Arduino boards. The control system you select should match both your technical comfort level and the functional requirements of your application—convenience features like memory positioning or synchronized multi-actuator control require more sophisticated electronics.
Power Supply
A properly rated power supply is critical for actuator performance and longevity. Your power supply must match the actuator's voltage specification (12V or 24V DC) and provide sufficient current capacity to handle the actuator's peak load. Undersized power supplies cause sluggish performance, overheating, and potential damage. Most residential and automotive applications use 12V DC systems, while industrial installations often prefer 24V for reduced current draw over longer wire runs.
Kit Option 1: Classic Actuator Basic Manual Control
This entry-level configuration provides everything needed for straightforward linear motion control. It's the most economical starting point and ideal for first-time builders, simple automation projects, or applications where wireless control isn't necessary.
Kit Components:
- Classic series linear actuator (multiple stroke lengths, speeds, and force ratings available)
- Manual DPDT rocker switch for extend/retract control
- Two MB1 mounting brackets with hardware
- 12V DC power supply appropriately rated for actuator current draw
The Classic series actuators represent FIRGELLI's core product line, offering proven reliability for residential and light commercial applications. These units feature internal limit switches that automatically stop motion at full extension and retraction, protecting both the actuator and your project from damage. Force options typically range from 50 to 400 lbs depending on the model selected, with stroke lengths from 2 inches to 24 inches available.
The manual rocker switch provides intuitive tactile control—press one direction to extend, the other to retract, and release to stop. This simple interface works well for applications like adjustable workbenches, motorized hatches, camper modifications, or any project where the operator maintains line-of-sight to the moving element.
Best Applications: Workbench height adjustment, RV vent operation, boat hatch automation, adjustable shelving, basic robotics projects, prototype development
Kit Option 2: Premium Actuator Basic Manual Control
This configuration upgrades to FIRGELLI's Premium actuator series while maintaining simple manual control. The Premium line offers enhanced durability, higher force capacity options, and improved sealing for demanding environments.
Kit Components:
- Premium series linear actuator with superior force and durability specifications
- Manual DPDT rocker switch for extend/retract control
- Two heavy-duty mounting brackets compatible with Premium series
- 12V DC power supply matched to actuator requirements
Premium actuators feature reinforced internal components, enhanced gear trains, and superior ingress protection compared to the Classic series. These units excel in applications involving heavier loads, more frequent cycling, or exposure to dust, moisture, and temperature extremes. Force ratings in the Premium line can exceed 1,000 lbs in certain models, making them suitable for industrial automation, agricultural equipment, marine applications, and heavy furniture systems.
The control interface remains straightforward with manual switching, but the upgraded actuator provides peace of mind for projects where failure isn't an option or where operating conditions are challenging. Premium actuators also tend to operate more quietly due to precision-machined components and better internal tolerances.
Best Applications: Heavy-duty TV lifts, industrial workstations, agricultural machinery, marine equipment, security shutters, commercial furniture, high-cycle-count applications
Kit Option 3: Classic Actuator Wireless with Adjustable Limits
This advanced configuration adds wireless convenience and customizable travel limits to the Classic actuator platform. It's ideal for applications where physical access to controls is impractical or where you need to fine-tune the actuator's range of motion.
Kit Components:
- Classic series linear actuator
- Two-channel wireless remote control system
- EL-Kit external limit switch module
- Two MB1 mounting brackets
- 12V DC power supply
The wireless remote control system liberates you from hardwired switches, enabling convenient operation from across the room or from positions where you can better observe the moving mechanism. This proves invaluable for applications like TV lift systems in entertainment centers, motorized window treatments, or any installation where running control wiring is impractical.
The EL-Kit external limit switch module represents a significant functional upgrade. While linear actuators include factory-set internal limits at full extension and retraction, many applications don't require the full stroke length. For example, you might purchase a 12-inch stroke actuator for a project that only needs 9 inches of travel, or you may want to prevent a mechanism from fully closing to maintain ventilation. External limit switches allow you to define custom stopping points anywhere within the actuator's range, effectively creating a custom stroke length without replacing the actuator. This feature also enables "soft start" positions and multi-position control for applications requiring intermediate stopping points.
Best Applications: Hidden TV installations, automated window treatments, home theater systems, adjustable ventilation systems, pop-up displays, motorized cabinets, applications requiring custom travel ranges
Kit Option 4: Premium Actuator Wireless with Adjustable Limits
This top-tier configuration combines the rugged capabilities of Premium actuators with wireless convenience and adjustable positioning control. It represents the most versatile and capable kit offering for demanding applications.
Kit Components:
- Premium series linear actuator with enhanced force and durability
- Two-channel wireless remote control system
- EL-Kit external limit switch module
- Two heavy-duty mounting brackets
- 12V DC power supply matched to Premium actuator specifications
This kit configuration provides professional-grade performance with user-friendly operation. The Premium actuator handles substantial loads and harsh conditions while the wireless control system enables convenient operation from a distance. The external limit capability allows for precise position customization—critical in applications like adjustable industrial equipment, automated access systems, or sophisticated home automation projects.
For example, in a commercial TV lift installation for a conference room, the Premium actuator's higher force rating easily handles large display panels, the wireless remote allows presenters to control the display from the podium, and external limits ensure the TV stops at the perfect viewing height without obstruction from ceiling fixtures. Similarly, in automated agricultural equipment, the Premium actuator withstands outdoor conditions while external limits prevent over-travel that could damage crops or structures.
Best Applications: Commercial automation, large-format TV lifts, industrial adjustable equipment, marine installations, automated access control, specialty vehicles, professional A/V installations, architectural mechanisms
Beyond Standard Kits: Customization Options
While the four kit configurations above address most common applications, linear actuator systems can be tailored further to meet specific project requirements. Understanding available customization options helps you optimize your system.
Alternative Bracket Styles
Different mechanical arrangements require different mounting bracket configurations. Clevis brackets with pivoting joints accommodate angular motion, fixed brackets work for straight push-pull applications, and specialty brackets adapt actuators to unique structural interfaces. When working with heavier loads or higher forces, upgrading to reinforced bracket designs prevents mechanical failure at the mounting points.
Advanced Control Systems
For applications requiring automation, synchronized multi-actuator control, or integration with existing building management systems, programmable controllers offer maximum flexibility. Arduino-based control systems enable custom logic programming, sensor integration, and automated sequences. Feedback actuators with built-in position sensors provide closed-loop control for applications demanding precise positioning or coordinated movement of multiple actuators.
Specialized Actuator Types
Beyond Classic and Premium series, FIRGELLI manufactures specialized actuator designs for specific applications. Track actuators integrate guide rails for lateral load resistance, bullet actuators provide compact form factors for space-constrained installations, and industrial actuators deliver maximum force and durability for demanding commercial environments.
Voltage Considerations
While most kits default to 12V DC (compatible with automotive and marine electrical systems), 24V DC operation offers advantages for installations with long wire runs or multiple actuators. Higher voltage reduces current requirements, allowing smaller wire gauges and minimizing voltage drop over distance. Ensure your power supply, control system, and actuator all share the same voltage specification.
Selecting the Right Kit for Your Project
Choosing between kit configurations depends on several project-specific factors. This decision framework helps identify the optimal starting point:
Start with a Basic Manual Kit (Option 1 or 2) if:
- You're building your first linear actuator project and want minimal complexity
- Manual control with tactile feedback suits your application
- The operator maintains visual contact with the moving mechanism
- Budget considerations prioritize essential functionality
- Your project involves light to moderate loads (use Option 1 for Classic, Option 2 for Premium based on force requirements)
Upgrade to a Wireless Kit (Option 3 or 4) if:
- Running control wiring to the actuator location is impractical
- You need to operate the mechanism from multiple locations
- The application benefits from remote operation (hidden installations, hard-to-reach locations)
- You require custom travel limits different from the actuator's full stroke
- Your project involves integration into home automation or smart control systems
- Again, choose between Classic (Option 3) and Premium (Option 4) based on force and durability requirements
Force and Durability Considerations:
The Classic vs. Premium decision hinges primarily on load requirements and operating environment. Classic actuators handle most residential and light commercial applications excellently. Upgrade to Premium actuators when:
- Moving loads exceed 400 lbs
- The actuator will cycle frequently (thousands of operations annually)
- Operating environment includes moisture, dust, temperature extremes, or corrosive atmospheres
- Application criticality demands maximum reliability
- Quieter operation is important for residential installations
Installation Best Practices
Even the highest-quality components won't perform well if improperly installed. Follow these engineering-proven practices for reliable, long-lasting operation:
Mounting Alignment: Actuators must mount with proper alignment between the fixed and moving points. Misalignment causes binding, uneven wear, and premature failure. Use a straightedge or laser level during installation to verify the actuator's stroke path aligns with the intended motion. Side loading—forces perpendicular to the actuator's stroke direction—dramatically reduces service life and should be minimized through proper bracket selection and alignment.
Electrical Connections: All electrical connections should be secure, properly insulated, and protected from environmental exposure. Use appropriate gauge wire for the current requirements—undersized wire causes voltage drop that reduces actuator performance. For mobile or outdoor installations, use marine-grade connectors and heat-shrink tubing to prevent corrosion. Always verify polarity before applying power; reversing power supply connections won't damage the actuator but will invert control direction.
Load Considerations: Actuators perform best when forces align with their stroke axis. Pushing applications generally allow higher forces than pulling applications due to the mechanical advantage of compression. When possible, design your mechanism so the actuator pushes rather than pulls. For applications involving significant offset loads or side forces, consider using slide rails or linear guide systems to carry lateral loads independently of the actuator.
External Limit Switch Installation: When installing external limits with the EL-Kit, position the switches to trigger slightly before the desired stopping point—this accounts for momentum and control system response time. Secure switches firmly to prevent position drift from vibration. Test limit switch operation thoroughly before final assembly to ensure they stop motion at the intended positions. External limits should always be wired as normally-closed switches to provide fail-safe operation—if a wire breaks, the system stops rather than continues moving.
Troubleshooting Common Kit Issues
Understanding typical problems and their solutions minimizes frustration during installation and operation:
Actuator Moves Slowly or Lacks Power: This usually indicates insufficient power supply current, excessive load, or poor electrical connections. Verify your power supply can deliver the actuator's peak current draw (check specifications). Inspect all wire connections for corrosion or loose terminals. Ensure the load doesn't exceed the actuator's force rating for your application's duty cycle.
Actuator Runs Backwards: Simply swap the two motor leads to reverse the actuator's direction relative to control inputs. This is normal during initial setup—polarity conventions vary between control systems.
Intermittent Operation: Typically caused by loose connections, inadequate power supply capacity, or thermal overload. Check all electrical connections for security. Verify the power supply isn't dropping voltage under load. If the actuator feels hot to the touch, you may be exceeding its duty cycle rating—allow cooling between operations or upgrade to a higher-capacity actuator.
Actuator Stops Short of Expected Travel: Internal thermal overload protection or external limit switches may be triggering prematurely. Allow the actuator to cool and retry. If using external limits, verify they're positioned correctly and wired properly. Check for mechanical binding or misalignment that increases load unexpectedly.
Wireless Remote Doesn't Work: Ensure the receiver has power and check that the remote battery isn't depleted. Verify antenna connections on the receiver module. Most wireless systems require initial pairing—consult the included instructions for the pairing procedure specific to your remote system.
Expanding Your System
Many projects evolve beyond their initial scope. FIRGELLI's modular component approach facilitates system expansion and enhancement:
Adding More Actuators: Multiple actuators can operate from a single control system with appropriate relay or control box configurations. For applications requiring synchronized movement of multiple actuators—like adjustable tables or coordinated doors—specialized controllers ensure all actuators start and stop together despite minor manufacturing variations.
Upgrading to Programmable Control: Once you've mastered basic operation, you might want automated sequences, sensor-triggered actuation, or integration with home automation systems. Arduino microcontrollers provide an accessible entry point for custom programming, while feedback actuators enable precise position control and coordinated multi-actuator movements.
Integrating Position Feedback: For applications requiring precise positioning or synchronized operation of multiple actuators, upgrading to feedback actuators with built-in potentiometers or Hall effect sensors enables closed-loop control. This proves essential for applications like adjustable standing desks with memory positioning or industrial automation requiring repeatable positioning accuracy.
Conclusion
A well-configured linear actuator kit eliminates the guesswork from motion control projects, providing compatible components that work together seamlessly. Whether you're starting with basic manual control or implementing wireless operation with custom positioning, selecting the appropriate kit configuration ensures your project starts on solid ground.
The four kit options outlined—from basic manual control with Classic actuators to wireless Premium systems with adjustable limits—cover the vast majority of residential, automotive, marine, and light commercial applications.

And with FIRGELLI's modular approach, your system can evolve as your needs grow or your expertise advances.
Frequently Asked Questions
What is the difference between Classic and Premium linear actuators?
Classic actuators represent FIRGELLI's core product line, offering reliable performance for residential and light commercial applications with force ratings typically ranging from 50 to 400 lbs. Premium actuators feature reinforced internal components, enhanced gear trains, superior sealing for harsh environments, and force ratings that can exceed 1,000 lbs in certain models. Premium units also provide quieter operation, longer service life under heavy cycling, and better resistance to dust, moisture, and temperature extremes. Choose Classic actuators for most standard applications and upgrade to Premium when you need higher forces, more frequent operation, or enhanced environmental protection.
Can I use a linear actuator kit with different voltage systems?
Linear actuators are voltage-specific—a 12V actuator must be powered by a 12V supply, and a 24V actuator requires 24V. Applying incorrect voltage will either underperform the actuator (lower voltage) or potentially damage it (higher voltage). Most FIRGELLI kits default to 12V DC, which is compatible with automotive, marine, and RV electrical systems. However, 24V systems offer advantages for installations with long wire runs or multiple actuators, as higher voltage reduces current requirements and minimizes voltage drop over distance. When configuring your kit, ensure all components—actuator, power supply, and control system—share the same voltage specification.
How do external limit switches work with linear actuators?
Linear actuators include factory-set internal limit switches that stop motion at full extension and retraction. External limit switches, included in Kit Options 3 and 4 with the EL-Kit module, allow you to define custom stopping points anywhere within the actuator's stroke range. For example, if you purchase a 12-inch stroke actuator but your application only needs 9 inches of travel, external limits can effectively convert it to a 9-inch stroke actuator. This feature also enables multi-position control and prevents mechanisms from fully closing when partial openings are desired. External limits are wired as normally-closed switches for fail-safe operation and can be positioned on your mechanism to trigger at any desired position.
Do I need mounting brackets, or can I fabricate my own?
While experienced fabricators can create custom mounting solutions, using purpose-designed brackets offers several advantages. FIRGELLI's mounting brackets are engineered specifically for their actuator models, ensuring proper load distribution, correct pivot geometry, and adequate strength for the actuator's force rating. They also provide correct hole patterns and spacing that simplify installation. Improper mounting is one of the most common causes of premature actuator failure—poorly designed or fabricated brackets can introduce side loading, misalignment, or inadequate strength. Unless you have specific mechanical requirements that standard brackets can't accommodate, using the recommended brackets ensures reliable installation and optimal actuator performance.
How many actuators can I control with one wireless remote?
The standard two-channel wireless remote systems included in Kit Options 3 and 4 can control multiple actuators, but configuration depends on your application requirements. If you want all actuators to move together in synchronized fashion—like adjustable table legs—you can wire multiple actuators to the same channel, though you'll need to ensure your power supply can handle the combined current draw. If you need independent control of different actuators—like separate control of a window and a vent—you would use separate channels for each function. For more complex applications requiring control of more than two independent actuator groups, multi-channel control boxes and remotes are available, or you can upgrade to programmable control systems using Arduino or other microcontrollers for virtually unlimited configuration possibilities.
