Hi Guys, Ive got a Furnas/Siemens 69MC8 Pressure switch for my minitruck..
I got the switch 2nd hand and im not 100% sure how to hook it up!
Its got 4 connectors.. Two 'Line' and Two 'Motor' connectors..
Then down on the pressure switch cassing - it has two Earth bolts.. Which im not sure if their needed or not.. (looks like their whats used to mount the switch to a bracket of some sort...
Anyways, Ive got TWO compressors that I want to run off the one switch..
Im guessing I need a Power from the Battery (to the switch), a power going to each compressor and an earth..
so WHAT is 'LINE' and whats 'Motor??
The switch I have looks exactly like the one at the top of this website:

You can see the 4 connectors up top.. Then down on the shell casing you can just see two Blue coloured screws that have an Earth sign next to them..
QUESTION: How do I hook it up?
any light on the subject would be great!
Thanks heaps!
