ZMA03A150L04RC is a subminiature snap-acting switch from the ZMA Series, featuring a single-pole double-throw (SPDT) momentary contact configuration with a 3.9 mm lever actuator and right-footed PC thru-hole termination. The switch is rated for 1 A at 24 V DC and 1 A at 125/250 V AC according to UL 61058-1, with an operating force of 150 grams. It incorporates silver alloy contacts, a PBT case, and nylon 6/6 actuator, delivering 1,000,000 mechanical life cycles and 300,000 electrical life cycles at 0.1 A. The device operates reliably across -40°C to +85°C, with 100 MO minimum insulation resistance and 500 Vrms dielectric strength, making it ideal for PCB detection, communication devices, testing equipment, and security/alarm systems where compact, reliable switching is required.
