I need a vacuum switch....you know one of those rack of switches behind the AC controls that switches vacuum on and off as directed by the AC/Heat system.
Does a 123 model uses these switches also?

I have a friend that has several 123s scrapped in his back yard and hope I can find one of the switches there.
Thanks
