The 7101SD9CQE is a single-pole, on-none-on miniature toggle switch from the C&K 7000 Series, featuring a single-pole double-throw (SPDT) configuration with three positions. The switch is equipped with copper alloy terminals with gold plate over nickel plate (B contact material) and an epoxy terminal seal for environmental protection. It operates over a temperature range of -30°C to 85°C with a contact resistance below 10 mO typical at 2-4 V DC with 100 mA, and provides an insulation resistance of 10? O minimum with a dielectric strength of 1000 Vrms minimum at sea level. The switch supports 40,000 electrical life cycles at full load and is RoHS compliant. Common applications include industrial control panels, instrumentation, and consumer electronics where reliable switching and compact form factor are required.
