The low pressure cut out switches fail in the open position quite often. I guess the contacts go bad. Unplug harness from switch and jump across plug with a wire or even large paper clip, see if compressor cuts in. Have engine running and A/C controls on. This is assuming you have enough charge to have the switch kicked in. Switch is closed but not passing current.
You can change Low pressure switch without dropping the refrigerant charge, it has a Schrader valve behind it. Have had to change two in the past year, on different vehicles.
A rule of thumb that I go by to see if you have close to proper charge is with system running, the suction line should be cool and 'sweaty' all the way from evap outlet to compressor. A set of gauges helps also! This is just one thing to check.
