The PAI LST-3608 is a stop light switch specified as normally open at 0 psig and closing at 5 psig. In heavy duty diesel truck parts, a pressure-operated stop light switch uses an air-pressure change to control the stop-lamp circuit, so these pressure points help distinguish the required switching function. MACK lists 1MR3544P2 as the OEM reference; additional MACK cross-references are 1MR1418R and 25158791.
