How To wire up a Square D Press Switch??

Looking to replace my Viair pressure switch with an ajustable square d.

Is it as easy as just removing the old, and installing the new, or does it get wired up completely different?

FYI the viair switch i am running now is the kind with built in relay.

Thanks

You hook up the power source(12volt) to one of the post and hook the compressors to the one right beside it.

good call on that. Square D P/Switches will last forever, way better than that garbage viair P/S.

but all you have to do is use one side of the switch,

So no built in relay like the Viair...

instead of using relays, we use Ford starter solenoids. They hold lots of power and can run a few compressors on one circuit.

Seen a few Square D's at Home Depot, are these the same as Suicidedoors and others sell? Im a bit pressed for time, and need one today, so thats why Im asking about the Depot ones.

yes, same thing. the same pressure switch on a big 80 gallon compressor and tank.
