Clarke Airmaster pressure switch internals?

[Debs.]

My Tiger 8/25 pressure control switch had become erratic and so I took the valve apart and the diaphragm out to remove the years of gooey-gunge....but, the torsion spring in the base of switch mechanism decided to fly off; I recovered it, but cannot for the life of me work out how it refits......

I`ve searched this part of the forum for a post I remember seeing, which showed a switch with the cover off; but, I can`t now seem to find it.

Might I ask, if a kind-soul has a similar compressor switch: could they take off the cover (the one with the 'red' on-off button on top) and take a close up of the switch mechanism internals: in particular, where the spring locates on the metal arms/lugs.

In case you need it , you can buy a new pressure switch complete from Machine Mart for £18 odd.

Thanks guys.....

I sat looking at it and the correct orientation 'spoke' to me......
The little joggled ends of the spring locate in the hole and slot (side nearest the camera) with the coil part of the spring naturally falling in the slotted part of the unloader arm (furthest from camera).....lots of spring force needed to be contained during reassembly and that would not have been possible without first removing the contact arm and contact block from the switch.
I`m an expert now!

All working fine and the hysteresis is minimal; it`s gone from a real-nuisance of a 70+ PSI lag, to now being about 25 PSI (i.e: from 'full/satisfied' to 'calling for refill').

Thats a first for me , I have never known a girly use the word hysteresis ever before !! waits for
