The 7211MDZBE is a dual-pole (DP), three-position miniature toggle switch from the C&K 7000 Series with an on-on-on switching function, designed for applications requiring simultaneous control of two independent circuits. This switch features a DPDT (double-pole, double-throw) configuration with connected terminals at positions 2-3 and 5-4, providing reliable switching across multiple positions. The switch incorporates an epoxy terminal seal for environmental protection and is rated for 40,000 electrical cycles at full load, with contact resistance below 10 mO typical and insulation resistance of 10? O minimum. It operates reliably over a temperature range of -30°C to 85°C and meets dielectric strength requirements of 1000 Vrms minimum at sea level. The 7211MDZBE is commonly used in industrial control panels, instrumentation, and equipment requiring multi-position switching with robust electrical performance and long operational life.
