Sometimes when folks install a switch for lighting they switch the neutral not the hot wire. Easy to check remove switch cover plate then switch from box. Using a volt meter, with switch in OFF POSITION check from each wire of the switch to a receptacle first to neutral then hot of the receptacle. If switch is wired correctly you should only get a voltage reading when going to the neutral side of receptacle. Hope that makes sense not hard to do David
