SQ Series Pressure Switch


The SQ Series pressure switch is available in a wide variety of configurations. The SQ pressure switch utilizes an internal diaphragm which is subjected to the process pressure through a connection in the application. A variety of fixed or adjustable ranges, and electrical connections, are available.

SQ series is a pressure switch product line using an internal diaphragm that is exposed to process pressure via the pressure switch threaded process connection. Opposing the diaphragm is a compression spring. When the process pressure is greater than the force of the compression spring the switch contact will open or close depending on the choice of the contact form. The SQ series pressure switch is typically used in a pressurized system to accommodate the sensing and controlling of process pressure within a defined or determined pressure range for the application process or use.
