12 Volt Single Socket and Wiring Harness For Single Pole Double Throw Relay

This wiring harness is needed for the Single Pole Double Throw Relay to make connection so much easier and mess free

This is a Simple quick connect Socket for the HFV4 relay These are a standard harness to fit the a SPDT 30/40 amp 12 volt relay sold separately Includes approx 10 of cable length

These can be used in a variety of ways, but this relay harness is a great way to control the DC motor of a linear actuator In order to achieve start/stop/direction control of a linear actuator you need to use two SPDT relays With the two SPDT relays you can cut the voltage/circuit to the motor and swap the polarity going to the linear actuator motor

Another advantage of using two SPDT relays to control a linear actuator is you get active or dynamic braking of the linear actuator allowing you to essentially stop on a dime

There are many other uses for relays, and this relay harness is a great way to wire up the relays
