I have a ceiling fan and light on the same switch.i want to change it to a double switch.?

i bought a double switch that fits in a single box.i am not sure how to wire it.i have a black,white and a ground from the light,fan and the breaker box.there are two screws on each side of the double switch and a ground screw.I have a ceiling fan and light on the same switch.i want to change it to a double switch.?You cant do it with that wire. You have a 12 or 14-2 with ground. You need a 12-3 with ground.I have a ceiling fan and light on the same switch.i want to change it to a double switch.?The first guy is right. You need 1 more wire from the switch box to the fan.I have a ceiling fan and light on the same switch.i want to change it to a double switch.?you need a 14-3 wire to the fan it has red, white, black, ground. the red goes to the light black to fan white to netural .



at the switch end black from power goes to the side of switch that has 2 screws there will be a jumper across the screws .



the red from 3 wire on top for the light , black on bottom screw.



tie the whites together .I have a ceiling fan and light on the same switch.i want to change it to a double switch.?You cant do it you would need another wire. The easiest way to do that is to either buy a remote control to install in to the fan or a fan control which involves a control module being wired into the fan box and control in the switch location and this only requires the wires you have in place
