The PAI LST-3607 is a dual-circuit low oil pressure switch listed for miscellaneous Mack and Volvo applications. Its configuration includes one normally open circuit and one normally closed circuit, both at 0 psig, with actuation at 55 psig; the 12/24 V switch uses a 1/8-27 thread with locking compound. As heavy duty diesel truck parts, low oil pressure switches monitor an engine oil pressure condition and change circuit state at a defined pressure to support warning or control functions. MACK OEM reference 1MR2226 identifies the part, with HALDEX 13240A and 13255A as selected cross-references.
