12 Volt Single-Pole Double-Throw Relay SPDT Relay 20Amp
The FIRGELLI 12V DC 20 amp SPDT Relay is the best choice for single-pole double-throw relay applications. With five terminal points and a higher current capability than the industry standard, this relay offers reliable performance and easy installation. Perfect for electrical needs where one circuit is to be activated by voltage from another circuit. An excellent and versatile tool for any circuit.
SPDT (Single-pole double-throw) relay comes with five terminal points. SPDT relay is very useful in various applications because of its internal configuration.
With a higher current capability than the respected industry standard Bosch relay, the FIRGELLI SPDT relay is the best choice for your single-pole double-throw relay needs!
FIRGELLI 12V DC 20 amp SPDT Relays are widely used in electrical applications where one circuit is to be energized or turned "on" by the presence of a voltage, provided by another circuit. An example of this is when a projector turns on it has a 12V signal to let different accessories know it's on. Anywhere a switch can go in a circuit, a relay can replace it, (as long as there is a triggering voltage available to activate it).
The "switch" in a relay is more often called a solenoid or coil. A solenoid is like a piston that pushes outward when energized with electricity. This push mechanically trips the switch in the relay, completing circuit and allowing the switched voltage output.
A relay can be triggered with an electrical pulse as small as 75 mili-amps. The switched output can be as high as 20 amps or more. One very useful use of a relay is to control a high current device such as a linear actuator motor with a low current signal, such as a projector or home theater controller. Another common use for relays is to separate control voltage from motor voltage. This is useful when you've got a control voltage of 12V and you want to control a linear actuator running on 36V.
- Hermetically sealed plastic housing and high-quality copper coil windings
- High-current contacts and are manufactured under strict ISO standards
- 20 Amps
- 5-Pin Relay SPDT 30/40A Bosch Type.
- 20 amps on the normally open contact leg (87), and 20 amps on the normally closed contact leg (87a).
- For DPDT (Double Pole Double Throw) relay
- For DPDT Timer relay
Typically Relays are used to turn on or off a motor or an Electric Linear Actuator where a signal is provided from another device to trigger the relay and that connects the power to the Actuator or motor.
