The M2012SS1W01 is a single-pole double-throw (SPDT) miniature Toggle Switch with solder lug terminals, ON-NONE-ON function, 0.413-inch (10.5mm) bat small toggles and 0.350-inch (8.9mm) threaded with keyway small bushings. The M series toggle switch has diallyl phthalate resin (UL94V-0) case, brass with chrome plating toggle and brass with nickel plating bushing. The anti-jamming design protects contacts from damage due to excessive downward force on actuator. The high torque bushing construction prevents rotation or separation from frame during installation. The high insulating barriers increase isolation of circuits in multi-pole devices and provide added protection to contact points.
