DSP Pressure switches are ideally suited for use on all types of engines, pumps, compressors, gearboxes, industrial power plant and other applications where resistance to the elements is the primary consideration.

Physical Description

The DSP consists of a single compact non-adjustable unit based on a 24 A/F hex brass body. This enables the control to be fitted directly into the application. The DSP senses pressure through a small orifice at the base of the thread.

Reliable electrical connection, in the toughest of conditions, is made using a Deutsch DT 2-way connector. IP67 rated, this connector is hot pressure washer resistant and is used by leading automotive manufacturers.


Should a hazardous condition arise, the DSP can be arranged to operate an alarm or initiate a shutdown at a pre-determined operating pressure, preventing damage to valuable plant machinery.

Installation Considerations

Check there is enough clearance around the flats of the body and ensure the maximum possible pressure is not exceeded for a long service life.

The DSP has a differential of 0.15 bar and provides automatic reset upon application pressure drop. For accurate pressure measurement, reliable connection and Ingress Protection, it is essential that genuine Deutsch DT connectors be used.
