Compressor with external tank build.

Spot on.. you have it in the power line between switch and main power relay so it overrides the switch once up to pressure. Then the master switch cuts all power, and the main relay does its stuff..

While my trol is off the road I'm fitting an endless air setup. Unsure if ill run a tank as the pressure and supply capability of the air con pump is insane...
Ill be going a 150psi cutoff, but the pump is capable of 400+ psi and even higher flow, so I should be aired up in under 5 mins.. love it..

This is Image is the best to get an understanding, I've just used a different kind of pressure switch.

The only problem with that wiring diagram is that it is a Switch to Earth (negative switching circuit) and I am not a fan to be honest.

I would be way more inclined to install a positive switching circuit so on a worst case basis you cut supply and there is no way you compressor can find an earth to keep running.


I would put your switch and your pressure switch into 86 for direct control of your relay.
