StarTeck,thanks for the reply.I forgot to mention that I am looking at the interior of the switch.I am wondering if the horizontal line that is shown within the interior of the schematic connecting the black contacts moves with the plunger, or is it a stationary.The interlock switch mounting should not be moving and no the wiring connector housing is not permanently attached. This is a 4 wire connection using either a keyed 4 position connector housing or a 5 position connector housing. Both could have been used over time.

The switch is normal mounted stationary as if moving constantly the wiring would break quickly over time due flexing back and forth.
