The 30-251-RED is a normally open, single-pole single-throw (SPST) pushbutton switch with a red actuator. It is rated for 1 Amp at 115 Vac resistive and 0.5 Amp at 220 Vac resistive, with an operational life of 250,000 cycles at the rated load. This momentary action switch requires an actuating force of 30 ± 8 oz and has a total travel distance of 0.062 ± 0.020 inches. Featuring a sealed bushing with an O-ring and a snap-on cap, it is designed for reliability in various environments, making it suitable for industrial controls, test equipment, and other demanding applications.
