BOSS Extra Heavy Duty 12V 24V Relay Solenoid to suit PX07 / PX02 Air Compressors

Our compressors are serious units and draw a lot of power. And so you need a man size relay that's not going to overheat. These units were originally designed for joining batteries, starting engines and operating winches, etc.

The old units we once sold earthed through the mounting feet. This unit now has a dedicated earth post. This is because people sometimes mount these into timber drawer systems or onto frames that dont have good earth.

It doesn't matter which way round you use the switching posts as the earth is now independent of the body. 

2 possibilities for setting up the solenoid as per our images

There is the conventional "Positive Switching" which supplies power to the application.

Earth switch which basically turns the earth on and off and that ensures most volts at the application and less heat and current through the solenoid. 

The trigger process (dash switch) has to be 12V but you can pass 24V through it (Battery to Compressor)
