Door Contacts.

The door contacts for the dome light aren't really designed to be serviced, but the spring in one of mine had snapped, requiring either replacement of the entire switch, or figuring out some way to disassemble and repair the assembly.

I opted for the latter and found that, after carefully filing away the rivet at the rear of the assembly, it was possible to disassemble the contact into its component parts.

from left to right: new screw (with allen wrench attached), new plastic washers, copper contact, plastic insulating spacer, fiber washer, switch body, spring, plunger (drilled and tapped)

I cleaned up the copper contacts, replaced the spring, and reassembled. I drilled and tapped the end of the aluminum plunger, and replaced the rivet with a small screw, using a stack of two plastic washers to hold the copper contact in place while insulating it from the rest of the switch.
