How to choose the correct actuator wiring diagram
Use the generator above to match the number of actuators, movement style, control method, and add-ons in your project. The wiring diagram should be chosen after you know the actuator voltage, current draw, control hardware, and whether the actuators need to move together or independently.
Most wiring mistakes come from treating the actuator like a small signal device. A linear actuator is a motor load, so the power supply, switch, relay, and wiring must handle the current at startup and under load. If the actuator stalls, binds, or reaches a hard stop, current can rise quickly. Choose components with suitable ratings and use the correct fuse or protection where required.
| Project detail | Diagram choice | What to verify |
|---|---|---|
| One actuator with manual control | Single actuator switch or relay diagram | Voltage, polarity, switch current rating, fuse, and wire gauge. |
| Two actuators moving one load | Synchronized control or feedback-capable diagram | Actuator feedback type, control box compatibility, equal mounting geometry, and load sharing. |
| Remote control required | Remote receiver diagram | Receiver current rating, supply voltage, antenna clearance, and fail-safe behavior. |
| Limit switches or safety stops | External limit or protection diagram | Normally open versus normally closed wiring, travel limits, and current path at end of stroke. |
| Long wire run | Diagram plus wire-size check | Voltage drop, current rating, connector quality, and routing away from sharp edges. |
Electrical checks before wiring
Confirm the actuator label or product page for voltage and current. Size the power supply for the total current of every actuator that may move at the same time. Use wire that can carry the load without excessive voltage drop. Confirm the switch, relay, receiver, or controller is rated for DC motor current, not just a low-current signal.
For reversing polarity, use the diagram exactly. Swapping polarity reverses actuator direction, but an incorrect relay or switch layout can short the supply. For multi-actuator systems, avoid simply wiring units in parallel if they must stay aligned under a shared rigid load. Feedback and synchronization are the safer path when uneven movement could bind the structure.

Wiring FAQ
Can I use any switch with a linear actuator?
No. The switch must be rated for the actuator voltage and current. A small signal switch should drive a relay or controller rather than the actuator motor directly.
Why do two actuators need synchronization?
Two actuators can move at slightly different speeds under load. Feedback and a synchronization controller help keep a shared panel, hatch, or platform square.
What causes slow or weak actuator motion?
Common causes include undersized power supplies, voltage drop from long or thin wires, poor connectors, overloaded actuators, or mechanical binding.
