The 200MSP3T1B1M2QEH is an SPDT (Single Pole Double Throw) momentary pushbutton switch designed for panel-mount applications. It features a 3-position operation with momentary switching action, silver-plated contacts, and an epoxy seal for environmental protection. The switch is rated for 3 amperes at 120 VAC or 28 VDC, with a maximum of 1 ampere at 250 VAC, and offers an electrical life of 30,000 make-and-break cycles at full load. It operates reliably across a temperature range of -30°C to +85°C with an insulation resistance of 1,000 MO minimum and dielectric strength of 1,000 V RMS at sea level. This switch is ideal for industrial control panels, instrumentation, and applications requiring robust momentary switching with high reliability and long operational life.
