HBS2KGB4STS41C is a single-pole standard precision snap-acting switch from the HB Series, designed for reliable switching in industrial control, motor, and thermostat applications. The switch features a sealed actuator and case that protects against airborne contaminants and splashing liquids, with an electrical life rating of 150,000 cycles at 20 AMPS @ 250 V AC. It offers low differential travel and high repeatability, with contact ratings from low level to 20 AMPS @ 480 V AC, an insulation resistance of 1,000 MO minimum, and dielectric strength of 1,500 Vrms minimum at sea level. The operating temperature range spans -55°C to 150°C (-67°F to 302°F), and the switch operates with forces ranging from 4 oz to 26 oz maximum at the actuator button. These characteristics make it suitable for demanding industrial environments requiring precision switching with long operational life.
