The 7101P3YZBE is a single-pole, on-none-on miniature toggle switch from the C&K 7000 Series, designed for reliable switching applications requiring compact form factor and anti-rotation capability. This switch features a flattened, anti-rotation P3 actuator standing 0.450 inches high, paired with a Y-series keyway bushing (0.350 inches high) for secure panel mounting with a 1/4-40 UNS-2A threaded interface. The switch utilizes copper alloy terminals with gold plate over nickel plate (B contact material) or silver-plated copper alloy (Q contact material), sealed with epoxy, and achieves contact resistance below 10 mO typical at 2-4 V DC with 100 mA. Electrical specifications include a maximum contact rating of 0.4 VA at 20 V AC/DC for B contacts, 100,000 make-and-break cycles at full load, insulation resistance of 10? O minimum, and dielectric strength of 1000 Vrms minimum at sea level. Operating temperature range spans -30°C to +85°C, making this switch suitable for industrial control panels, instrumentation, and consumer electronics requiring reliable, compact switching with anti-rotation features.
