Light switch trips beaker when turned ON

I swapped out 2 ceiling fans yesterday (I've installed dozens of fans and never had a problem). This required removing the slider type switch and installing the regular toggle type switch (this part I have not done before). I believe I have the wiring hooked up correctly, although I didn't have a previous wiring like this to copy. It's a double switch where one controls the fan and the other controls the light. The fan works just fine but the split second I flip the light switch, it trips the breaker.

There are 3 white wires all bound together tucked in the back of the box, 3 black wires to hook up, one of which is coming from the other light switch. And of course the ground, which are obvious to me where to connect.

Oh and the house is 7 yrs old.

Any ideas?

You have a short. You might have something touching something it shouldn't be inside the box your switches are in. I have found that a lot of times the ground wire may come into contact with a terminal when you push the switch back into the box.

If everything is free and clear you might have made a mistake when you hooked everything up.

Thanks for the response. That's what I was starting to think too. I'm going to check the fan and see if something is touching up there when I closed it up. I tested the switches before closing them up, so I know nothing was touching there.

You hooked up the switch leg for the switch incorrectly. Take it apart and fix up in the junction box, or if you messed with the switch, double check that also.
