The 1003P1T1B4M7QE is a 3PDT (three-pole, double-throw) toggle switch designed for PC board mounting applications. It features three switching positions (ON-NONE-ON) with 9 terminals (2-3, 5-6, 8-9 in position 1; open in position 2; 2-1, 5-4, 8-7 in position 3), silver-plated contacts, and an epoxy seal for environmental protection. The switch is rated for 2 Amps at 250VAC or 5 Amps at 120VAC/28VDC, with an electrical life of 40,000 make-and-break cycles at full load and an insulation resistance of 1,000 Megaohm minimum. Operating over a temperature range of -30°C to +85°C with dielectric strength of 1,000 V RMS at sea level, this switch is ideal for industrial control panels, instrumentation, and consumer electronics requiring reliable multi-circuit switching with RoHS compliance.
