The 7107P3YZQE is a single-pole, on-off-momentary (SP On-Off-Mom.) miniature toggle switch from the C&K 7000 Series, featuring a flattened anti-rotation actuator (P3) at 0.450" high and a keyway bushing (Y) at 0.350" high. The switch employs an epoxy terminal seal and copper alloy contacts with silver plating, delivering contact resistance below 10 mO typical at 2-4 V DC with 100 mA. It is rated for Q contact material at 5 amps @ 120 V AC or 28 V DC, with an electrical life of 40,000 make-and-break cycles at full load, an insulation resistance of 10? O minimum, and dielectric strength of 1000 Vrms minimum at sea level. Operating across -30°C to 85°C, this switch is ideal for control applications in industrial equipment, consumer electronics, and instrumentation where reliable switching and anti-rotation features are required.
