Ceiling fan switch: no ground wire
I'm changing a wall switch, which controls a ceiling fan and light (two separate controls on the switch). The switch I bought said it can be wired to all existing fan/light wiring. It has three wires coming out of it: fan, light, power(hot). The old one had four wires: fan, light, power, ground. The new one does not have a ground wire or even a terminal to connect the bare ground wire that used to be connected to the green ground of the old switch. Did I get the wrong switch or am I to simply connect the bare ground wire to the screw holding the new switch box to the wall box? Thanks!
