There is no such switch that does what was described. The are 2 pressure
switches but they do something else. The low pressure switch disables
the compressor when there is not enough freon in the system. The high
pressure switch turns on the radiator fan medium speed when the /C is
working hard enough to need it.

The only other switch that disables the compressor is the radiator high
temp switch. When the radiator temp is too high it turns on the high
speed rad fan and disables the compressor to reduce the heat load.
