The 7401SPYZQI is a 4-pole double-throw (4PDT) miniature toggle switch from C&K Components' 7000 Series, designed for on-none-on switching functionality. This switch features an anti-rotation actuator with a height of 0.420 inches and operates over a temperature range of -30°C to 85°C with a contact resistance below 10 mO typical at 2-4 V DC and 100 mA. The switch is rated for 40,000 electrical cycles at full load, with a dielectric strength of 1000 Vrms minimum at sea level and an insulation resistance of 10? O minimum. It includes an epoxy terminal seal and is compatible with bottom-wash PCB cleaning methods, making it suitable for industrial control panels, instrumentation, and consumer electronics requiring reliable multi-pole switching with compact form factor.
