The switch I believe you are referring too is the loss of charge switch it should be located in the liquid line not the suction line. It would be best to have a set of gages on the system and jumper out the loss of charge switch then add refrigerant till the low pressure gage reads about 25# with the engine rpm around 1500. I suspect you may have a fair sized leak if the loss of charge switch is shutting off the compressor.. it will be easer to diagnose the problem with the switch jumped and the high and low pressure readings with the engine running.
