Cherry has updated its GP Series precision snap-action switch with UL current ratings of 20 amps at 125VAC and mechanical endurance of more than 1 million cycles. The company says the switches are suited for heavy-duty commercial and industrial applications such as factory automation, industrial vehicles, elevators and valves.

Horsepower ratings are 1 hp at 125VAC and 2 hp at 250VAC; previous versions of the GP Series switch were UL-rated to 15 amps. The switch is housed in a phenolic case measuring about 1.9 inches long, 0.9 inch high and 0.7 inch wide.

Cherry offers 13 different standard actuator styles, including nickel-plated steel levers, rollers and buttons. Brass screw terminals and copper alloy solder terminals are standard. According to the company, temperature rating is -20 Celsius to + 85; initial contact resistance is .015 ohms max; and insulation resistance is 100 mega ohms min at 500VDC.
