Profile: JMP Switches, A Division of Senasys specializes in offering different types of switches. Plunger switch is a basic micro switch. When little force is applied to the plunger the micro switch actuates controlling the equipment or appliance. Available with multiple mounting options. Base series are designed for operating temperatures up to 150°F. The float/condensate switch is designed to shut off a pump or system when a liquid level rises. As the liquid level rises, the stainless steel leaf with a styrene float applies pressure to the micro switch plunger. Once the micro switch is actuated, the system shuts down to prevent the water level from rising. Available in multiple mounting designs.
