•  The refrigerant pressure switch is used to interrupt A/C compressor operation in the event of high system discharge pressure.

•  The refrigerant pressure switch is mounted on a Schrader valve-type fitting on the high pressure side of the condenser to evaporator line.

•  A valve depressor, located inside the threaded end of the refrigerant pressure switch, is used to monitor the compressor discharge pressure.

•  It is not necessary to discharge the refrigerant system to remove the refrigerant pressure switch.

•  The refrigerant pressure switch has two sets of contacts. One electrical contact is normally closed.
