Pressure switches

Empowering performance

Pressure switches

All NRF pressure switches and sensors are manufactured to meet or exceed high expectations.

Competitive range
The NRF pressure switch range contains 65 references.

The function of a pressure switch
The function of pressure switches and sensors is to control the air-conditioning system pressure and to protect the compressor. Pressure switches are used on non-integrated systems and exist as binary (Low/High) or trinary (Low/Mid/High) versions. They are not only used as a low pressure (LP) or high pressure (HP) control device but also as a protective device.

In modern, integrated systems you will find pressure sensors which have the same function as the pressure switch (control- and protective device), but are communicating with the engine control unit (ECU) by sending either analogue voltage signals or digital PWM signals.
