The Bendix SL-4 Stop Light Switch is an electro-pneumatic switch that lights the stop lamps directly from brake application pressure on air-braked trucks and tractors. Air from the brake valve enters the cavity beneath its diaphragm, and once that pressure reaches 3 to 6 psi it overcomes the spring and closes the contacts. Plumbed into the brake chamber supply line, the Bendix K101996 responds whether the driver applies the foot valve or the hand valve. Bendix calls for checking switch operation and electrical connections at least every six months or 1,500 operating hours.
