Probably a switch cut in by the coach builder to cut off the compressor when heavy load (hill climbing). Helps keep your cooling system from overheating because a/c takes a lot of power.
The answer to leak is that it is under pressure whether turned on or not.
As mentioned above a good a/c shop can replace the switch for you. Be sure they are capable of saving the coolant (Freon or whatever is in your system) and recharge without having you pay for a full re charge, assuming it still gets cold.
This is one of those longer you wait the more it might cost things. Not crucial if you don't run the a/c, but could get expensive in a hurry if you do. :) :)
NO RV chassis(Gas or Diesel class A) has a system that cuts out the compressor under heavy engine load. The switch pictured is a Pressure switch and since it has 4 wires it does 2 things. IF the pressure drops(coolant leak) it cuts out the compressor, and it also activates the Condensor cooling fan. Doug
