The 8121J80ZGE2 is a single-pole, double-throw (SPDT) snap-acting momentary pushbutton switch from the 8020 Series, featuring a J80 snap-in front mount actuator with no frame color option. This switch delivers positive tactile feel and is designed for applications requiring reliable momentary contact switching. The switch offers contact ratings of 1 AMP at 120 V AC or 28 V DC (with G contact material), with contact resistance below 50 mO typical at 2-4 V DC and 100 mA. It provides an electrical life of 60,000 make-and-break cycles at full load, insulation resistance of 10? O minimum, and dielectric strength of 1,000 Vrms minimum at sea level. The switch features an epoxy terminal seal compatible with bottom wash cleaning and is commonly used in instrumentation, computer peripherals, and telecommunications equipment.
