What is this electrical thing?

Found this under the dash, behind the AM radio, of a 67 firebird I stripped today.
It's about the size of a silver dollar.
Anyone know what it is?

Re: What is this electrical thing?

It looks like the A/C compressor vacuum switch which mounts to the A/C heat controls right above the radio. Did this car have factory A/C?

Is there a switch that doesn't have electrical connections?

Re: What is this electrical thing?

I seem to remember when I was behind my dash in my '69 that there was a vac switch/valve (possibly a/c changeover) that looked similar to that one, yet had no elect. conns.
In an early Mercedes, we call them 'vacuum changeover switch'- sorry

Yes it had factory A/C, does look like a vacuum switch.
That sounds right. Thanks.

Re: What is this electrical thing?

My a/c switch looks nothing like that one. Mine is elec. connections only, rectangular shaped on drivers side of the panel inside the mechanism. The Vac connections on my a/c are on the opposite side of the panel on the outside of the mechanism, with hose bibs only, no elec. connections. I think that is from a different car.

Re: What is this electrical thing?

My '67 had just such a switch. When the temp lever was moved to the cold position, a vacuum switch on the control would activate both the recirculation door and the vacuum activated switch shown above which would turn on the compressor when the blower switch was on.

Mine gave up the ghost many years ago. I replaced it with a toggle switch which I much prefer. The downside is that I have to flip the toggle when I want A/C. The upside is that I can run the compressor with the defroster which improves its performance greatly.

Thanks - this switch does not hold vacuum anymore, and does not look like it can be repaired.

At least I know what the heck it is.
