The 7203SDW3QE is a dual-pole, on-off-on miniature toggle switch from the C&K 7000 Series, featuring a DPDT (double-pole, double-throw) configuration with on-off-on switching function. This switch is designed with an epoxy terminal seal and operates reliably over a temperature range of -30°C to 85°C, with a contact resistance below 10 mO typical at 2-4 V DC and 100 mA. The switch supports multiple contact materials including gold and silver options, with electrical ratings of 5 amps at 120 V AC or 28 V DC, and 2 amps at 250 V AC for Q contact material. It achieves 40,000 electrical life cycles at full load and maintains an insulation resistance of 10? O minimum with 1000 Vrms dielectric strength. The 7203SDW3QE is commonly used in industrial control panels, instrumentation, and consumer electronics applications where reliable switching and compact form factor are essential.
