There is an easy way to find out if they are pump switches. Turn them both off and open a faucet to let the pressure off of the system. If the pressure (water flow) does not stop and the pump runs, then that one is not a pump switch. If it does stop (water flow), then turn one switch on and listen for the water pump or also open a faucet and water should flow. It that works for you, then do the same for the switch in the outside shower. I do think that the switches are simply labeled wrong, but you will find out by doing this.
