How to disassemble door jamb switch?
« on: February 12, 2016, 07:32:25 PM »
I want to take this switch apart & find out why it isn't working. It's from a 1965 Cadillac. Anyone know how these come apart?

Probably made not to come apart. Bet they are glued together.

Just discovered a nice trick.   Soak the switch in white vinegar.  I just resurrected 2 63/64 door jamb switches by doing that.  Soaked for 3 hours, rinsed with brake parts cleaner.  Works perfectly.

Haven't tried the white vinegar method.

I did take a switch apart over the winter.

Carefully pry the top off with small screwdriver / pick. Using a hairdryer on low heat will soften the plastic and make it a little easier. Be patient.

Clean the switch especially the brass and copper parts.

Reassembly: Make a "jig" with scrap wood. Drill a 1/2" hole for bottom of switch in a 2" x 4" and a 3/8" hole for the plunger in a smaller piece of wood. Put the switch base in the 1/2" hole and the top part with the button in the 3/8" hole. Gently press the switch back together.

Lucas,
I have tried a similar approach to the vinegar Russ used (without taking the switch apart).
I use CLR - Calcium Lime Rust remover - sort of a clear to greenish liquid, into which I submerge the switch in a bottle of the stuff.
I guess I am more impatient, so I want fast.
During the marination process, shake the switch and liquid a number of times - let sit and repeat, and activating the plunger several times along the way, seems to do the trick.
Rinse with distilled water from the steam iron, and there you have it.
By the way, I use this approach with all manner of switches from the 40's to the 70's, and the light bulb sockets to clean the contact surfaces.
Have fun,
Steve B.
