are you sure the switch is your problem? I know the more common problem is the electric servo that is screwed into the front axle. you can check it by going under the passenger side of the truck at the "back" of the front axle just to the top right of the pumpkin there will be a plastic cylinder (about the size of a can of red bull) with a couple of wires coming out, undo the connector for the wires and unscrew the servo there usually not in that tight but you might need to use channel locks after you get it out plug the wires back in turn the key on and shift to 4x4 and go look at the servo the plunger at the end where you unscrewed it should be sticking out atleast 1.5 inches if not tap on it if it does not come out you need to replace it. if it works fine than its probably your switch as you said. you might find either one at a used vehicle salvage yard.( junk yard )
