Ignition Switch: Description and Operation
IGNITION SWITCHThe ignition switch contains the wiring and electrical switching portion of the column mounted ignition assembly. The ignition switch includes wiring pigtails which connect it to the base of column connector, the Passlock Sensor on the ignition lock cylinder case, and other components. The wiring for the Passlock Sensor is unaffected by ignition switch position. The electrical switch portion is operated by the key and lock cylinder when they are rotated within the ignition lock cylinder case. The ignition switch operates the crank relay regardless of the status of the Passlock System.
