Replacing light switch causes problem

Hi.

I replaced a light switch in a closet that had 3 wires (red,black&white). I rewired it the same way as the old switch, however, instead of using the push-in slots, I screwed the red and white wire to the post. On the black wire I did use the push-in slot. (I think this is correct, I'm not where I can double check my wiring right now)

The problem is a light switch in a bathroom near the closet now will not work. My wife told me that it was out, and when I went to check it... it worked !!! I went and checked the breakers to make sure nothing was tripped. This morning when I went to check it, it did not come on. I tried turning on the closet switch, thinking that it must be daisy chained to the bathroom switch, but the bathroom light still doesn't work. I have a meter to read voltage (and an upset wife) Any ideas ? Thanks in advance for any assistance.

A 3-wire cable connection,Black,White & Red, at a single-pole switch indicates that the Black & White wires may supply 120 volts from closet switch-to closet fixture-to bathroom switch or 120 volts from closet fixture-to closet switch-to bathroom switch.One end of the Red wire would connect to the switch terminal and the other end of the Red wire would connect to the fixture. The White wire would not connect to the switch if you have "standard" connections. Remove the 3 wires from the switch and check for 120 volts across the Black and White wires.Test across the Red and Black wires with a test-lamp socket. This should connect the test-lamp in series with the fixture lamp and both lamps will be dim because 120 volts is "divided" across the lamps. The circuit is: Black wire-test lamp-Red wire-fixture lamp-White wire.Please report back and ---Good Luck!!!
