Here is my Factory Driver Door Jamb Switch; Two pin/prong
My car is apart, and the switch was successfully sent to a plater for Clear Zinc plating. The bayonet plunger was stuck but was able to force apart to allow spring action and proper operation. The Zinc tank plating is a cold process and was NOT harmful to the insulating plastic internals.
Others with Parts books might have PN or repair service item PN, since this was part of the Body Harness and installed by Fischer it is Not Shown in the Factory AIM manual.
