The 200MSP1T1B1M2QEH is a single-pole double-throw (SPDT) panel-mount toggle switch designed for reliable switching applications. It features a 10-48 UNS-2A threaded mounting with an epoxy seal, silver-plated contacts, and is rated for 3 amps at 120VAC or 28VDC (1 amp at 250VAC). The switch operates over a temperature range of -40°C to 85°C and provides 6,000 electrical make-and-break cycles at full load with an insulation resistance of 1,000 megaohm minimum and dielectric strength of 1,000 V RMS at sea level. This switch is ideal for industrial control panels, instrumentation, and equipment requiring robust switching with high reliability and environmental durability.
