Vacuum switch
Posted: Tue Aug 22, 2006 12:18 pm
My Vac switch happened to be opened, so I opened it again and found a very simple device inside: its a hollow rectangular rubber block connecting or disconnecting the headlamp pods to the vac tank. It is moved back and for by the switch handle, pressed down by a leaf spring.
Leakage could come from rust on the metall surface where the rubber moves. The rubber could also cause leakage (was still perfect in my car),
even the angeled tube soldering could leak. Its all hand build and soldered
so can be repaired. The rubber could simply be cut from massiv rubber block. I hand grinded the metall sealing surface with 1000 grade paper on a block and had it regalvanized with zink. The cover can be opened by gently undoing the 4 top "rivetings". the undoing of the vacuum (lamps down) is via the housing slots so they need to breathe!
I could add a picture of what is inside.
