A/C/Heater control vacuum switch question

[Daniel Romero]

My vacuum switch broke on the heater and a/c control box. Mine is the first one pictured. I can’t find one on EBay that has the same numbers listed in red at the bottom and the top number is off by one letter. Do I have to find one that matches the numbers on mine or do I have some other options?

What are you working on? I think you've got some flexibility as long as the layout of the switch is the same. I had a switch break just like that years ago.

There were several minor variations of this switch, usually involving improvements, as long as it is correct for the application it should work. You have a 5 button switch and the replacement is also a 5 button unit so it should function the same.

Thanks, Dave!

I don’t want to shell out the prices they’re asking for on eBay and end up getting the wrong one.

How To Rebuild a Vacuum Heater Control Switch

 

[Gerald Morris]

Pity OER doesn't make a 4 button replacement. The only thing wrong w mine is that the button slides have crumbled at the ends. I've thought about using epoxy to make the lovely chrome buttons hold onto those buttons better, but hate using something like that. I do alright with the heater on one setting most of the year anyway, and merely varying the fan speed and the vent for getting air by the core....
