Here are some pics of a Z/A/B(C?) ignition switch I stripped down when changing lock barrels.
Removing the black plastic cover, I found nasties on the blade terminals
this corrosion with some nice dampness could lead to some interesting faults
The Switched Section
The copper contacts and wipers were all in good condition
and would be used again
Heavy scoring, pitting and tracking would be suspect.
DONT LOSE THE SPRINGS !!
These little buggers have a habit of jumping out from under the two wipers so Be careful.
Heres what all the contacts do electrically
RED - Supply from main fuse
GREEN - Earth/Ground via loom
BLACK - Supply out when ignition is switched on
BLACK/WHITE - Connected to ground when ignition is switched off.
Linked to killswitch which does the same job. Stopping engine
BROWN and BROWN/WHITE -lights/parking lights
Check the wiring diagram for your model
My wiring is home made and I dont use these connectors
