Does anybody know what the attached is

[JasonGhartey]

Can somebody please point me in the right direction? I am looking for the key switch in the pic below. Can anyone help? I think it may be an override switch or bypass switch. Any help would be greatly appreciated.

Looks to me like it might have been home made by the original installers. Are you sure it's faulty if you don't know its function? I'd suggest you should figure out what it does first the open it up and make a note the switch contact block arrangement and just replace the contact block or barrel and contacts if necessary.

I have to agree with the above it looks like a basic panel mount key switch but you would need to know it's function.
