The 7101TZQE is a single-pole, on-none-on miniature toggle switch from the C&K 7000 Series, featuring SPDT (single-pole double-throw) switching configuration. The switch is equipped with B contact material (copper alloy with gold plate over nickel plate) and an epoxy terminal seal for reliable performance. It operates over a temperature range of -30°C to 85°C with contact resistance below 10 mO typical and insulation resistance of 10? O minimum, providing robust electrical characteristics. The switch supports 100,000 make-and-break cycles at full load and features a dielectric strength of 1000 Vrms minimum at sea level. This switch is ideal for applications requiring miniature, reliable switching in industrial control, instrumentation, and consumer electronics where compact form factor and long operational life are essential.
