Pressure switches can be used in refrigeration and air conditioning systems to protect the systems from extremely low suction pressure or extremely high discharge pressure. The pressure switches are also used to start or stop the refrigeration compressors and air-cooled condenser fans, to regulate other components in the systems which require pressure control function.
- High level of accuracy and stable repeatability Long life timewith both excellent electric and mechanical reliability SPDT switch to ensure good contact and disconnect conversion with fast reactions Various pressure ranges are available Supply with standard plate for installation Bellow elements are made of Tin bronze and pressure connections are made of bras
