Pressure Switches

Pressure switches monitor the pressure level of a process and open or close electrical contacts at pre-determined set points. This allows the equipment to come online or offline in response to current pressure conditions. Pressure switches are ideal for ensuring pressure levels remain within ranges best suited for safety and production.
