Stoplight Switch: Saturn

  1. Loosen stoplight switch mounting nut enough to allow switch to move in adjustment slot. Install Adjustment Gauge (SA9303BR) between switch and actuator pad on brake pedal arm, ensuring switch plunger protrudes through slot in gauge.
  2. Pull up on brake pedal with moderate force while pushing switch forward against gauge.
    NOTE: It is important to hold switch perpendicular to actuator pad (maintaining alignment) while tightening mounting nut.
  3. Tighten switch mounting nut. Release brake pedal. With pedal released and adjustment gauge still in position, ensure gauge will swing freely. If gauge does not swing freely, repeat steps  1- 3 .
  4. With gauge still in position, pull up on brake pedal with very light force and tap gauge side to side. If gauge swings freely, repeat steps  1- 4 .
  5. Inspect switch plunger. If .040" (1.0 mm) or less of plunger is visible between switch and switch actuator pad, switch is correctly adjusted. Height of rounded crown of plunger is equivalent to .040" (1.0 mm). If more than .040" (1.0 mm) of plunger is visible, repeat steps  1- 5 .
