The 7211SDZQE is a dual-pole, on-on-on miniature toggle switch from the C&K 7000 Series, designed for reliable switching in compact applications. This switch features a DPDT (dual pole, dual throw) configuration with all three positions connected (on-on-on), providing continuous switching capability across all positions. The switch incorporates an epoxy seal for environmental protection, operates over a temperature range of -30°C to +85°C, and maintains contact resistance below 10 mO typical at 2-4 V DC with 100 mA. With an electrical life rating of 40,000 make-and-break cycles at full load, a dielectric strength of 1000 Vrms minimum, and insulation resistance of 10? O minimum, this switch is well-suited for industrial control panels, instrumentation, and consumer electronics requiring reliable multi-position switching.
