Single Lock - Phase 1
SINGLE LOCK - PHASE 1, MECHANICAL LOCK AT DOOR AND LOCK SIGNAL GENERATION
The lock button and key mechanically rotate the lock lever (yellow) which decouples the the exterior door handle from the latch.
When rotated, the lock lever (yellow) also slides an internal switch ramp (red) to the left closing the lock microswitch. This provides the lock signal to the module.
