It looks like a Ranco like I just replaced available from our host and others. Size wise it is like the currently available version. On the side in your pictures not shown was stamped Ranco as I recall.

So this is just and updated version of the OEM switch? Should it open up the compressor clutch circuit when turned to the full CCW position like the old ones did? When I check the continuity of my switch I get a closed circuit between the 2 spade connectors regardless of where the knob is positioned which is not what is supposed to happen according to the diagnostics checkout description on the Griffiths website. At the full CCW position I should get an open circuit which I do not get.

Roger,

Here's another pic.

This switch is about the same size as the one I replaced, however, the external configuration is a bit different.

Did you have to modify the switch housing to allow complete CCW rotation to the last dial marker?
