I almost posted here to ask if an ignition switch is repairable, and if so, what to expect inside. Since I have a new switch which refuses to mate with the old connector, even after removing all of the plastic surrounding the male pins, I decided to sacrifice it and see what's inside:
Here's the switch after carefully bending back the pot-metal tabs which hold the plastic base in place:
Base plate removed, showing contacts for each pin and the two "rotating" contacts:
Close-up of the two "rotating" contacts; these are spring loaded: "boing" alert:
After the "boinging" stops and all the little bits have been collected again:
Close-up of the rotating base. This is what your key cylinder rotates. You can see the spring which returns the switch to "Run" from the "Start" position":
Inside the metal housing:
Everything:
Now I will try to open up my old switch to see why it is giving me an intermittant contact.
Update:
I did the old switch this morning, here is a photo of the contact surfaces:
Cleaned it up, got it back together and it works. Time will tell if the intermittancy is corrected...
