The 7211LY9ABE is a miniature toggle switch from the C&K 7000 Series designed for three-pole (3P) switching applications with an ON-ON-ON function across all three positions. This switch features a 1/4-40 UNS-2A threaded mounting interface with a 25° keyway and connected terminals at positions 2-3, 5-4, and 8-7, providing simultaneous switching of three independent circuits. The switch operates reliably over a temperature range of -30°C to +85°C with contact resistance below 10 mO typical and an insulation resistance of 10? O minimum. With an electrical life rating of 40,000 make-and-break cycles at full load and dielectric strength of 1000 Vrms minimum, this switch is well-suited for industrial control panels, instrumentation, and equipment requiring multi-circuit switching with reliable, long-term performance.
