I'm replacing the light switch in my bath and bought a new switch, but
this one looks different than the old one I took out. It has three
screws two on the side and one green one on the top. THe old one only
had one on each side. Now I replaced the switch and hooked up the green
wire with the green (ground) screw on the top and the red wire on one
of the screws on the other side but its not working. I know the old
switch is broken cause when I hit the switch I can see that there is a
short in the switch when I wiggle it. But this new switch should work
right? What did I do wrong? Or should I just take it back and get
So you have a green wire and a red wire only? If you only have two wires,
then you don't have grounding support, and they should be connected to the
two side terminals. If there are three wires, then you'll want to connect

Are you saying you have just two wires, one green and one red??? That
is scary as you should never have just those two. You can have red and

live because someone screwed up. If the green was hot then you now have a
I would want to have someone with some experience check the mess out

DO NOT connect the green wire to the green screw! It could be very
dangerous, since it sounds like the green wire, in this case, may be
energized at line voltage. You have a wiring problem in your house, at least
with regard to wire colors. The two wires should be something other than
green. I strongly urge you to have an electrician check into this.
