The 100SP3T1B4VS2QE is a three-position SPDT (Single Pole Double Throw) toggle switch designed for panel-mount applications with a standard locking ring. It features a silver contact material and operates with three distinct positions: ON (connecting terminals 2-3), OFF (open circuit), and ON (connecting terminals 2-1), providing flexible switching functionality. The switch is rated for 2A at 250VAC, 5A at 120VAC, or 5A at 28VDC, with an electric life of 6,000 make-and-break cycles at full load and an insulation resistance of 1,000 MO minimum. Operating reliably across a temperature range of -40°C to 85°C with a dielectric strength of 1,000 V RMS at sea level, this switch is ideal for industrial control panels, appliances, and equipment requiring robust, multi-position switching with high reliability and long operational life.
