Brake Light Switch: Testing and Inspection

INSPECTION
STOP LIGHT SWITCH INSPECTION





Connect an ohmmeter to the stop light switch, and check whether or not there is continuity when the plunger of the stop light switch is pushed in and when it is released. The stop light switch is in good condition if there is no continuity when the plunger is pushed in to a depth of within 4 mm (0.16 inch) from the outer case edge surface, and if there is continuity when it is released. A continuity should be checked between connectors "a" and "b" of the stop light switch.
