The 1003P1T1B1M1QE is a 3PDT (three-pole double-throw) toggle switch designed for panel-mount applications with three distinct operating positions: ON, NONE (center off), and ON. It features a 1/4-40 UNS-2A threaded bushing with a 6.35 mm (0.250 in) diameter and is available with or without a standard locking ring for secure mounting. The switch is rated for 2A @ 250 VAC, 5A @ 120 VAC, or 5A @ 28 VDC, with silver contact material providing reliable electrical performance. It offers an electric life of 40,000 make-and-break cycles at full load, insulation resistance of 1,000 MO minimum, and dielectric strength of 1,000 V RMS at sea level, with an operating temperature range of -40°C to +85°C. This switch is ideal for industrial control panels, equipment switching, and applications requiring multi-position switching with center-off capability.
