Mechanical Pressure Switch AT-PS275
Mechanical Pressure Switch AT-PS275
AT-PS275 pressure switch is suitable for pressure detection and monitor in piping system, automobile braking system, air compressor, medical equipment and tire manufacturing industry. 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.
