The 7105SYCQE is a single-pole momentary-off-momentary (Mom-Off-Mom) toggle switch from the C&K 7000 Series miniature toggle switches, featuring SPDT (single-pole double-throw) switching configuration. The switch is equipped with an S actuator (0.420" high) and a Y bushing (0.350" high, keyway), with epoxy terminal seal and nickel-plated brass hardware. It operates reliably over a temperature range of -30°C to +85°C with contact resistance below 10 mO typical and insulation resistance of 10? O minimum, meeting a dielectric strength of 1000 Vrms at sea level. The switch is rated for 40,000 electrical cycles at full load and is RoHS compliant, making it suitable for industrial control panels, instrumentation, and consumer electronics requiring momentary switching action.
