I have a switch in bathroom that lights up my 25w florescent bulb. For
years I've used the up toggle switch to turn it on and down to turn it
off. Now, for the past week or so, its doing the reverse. It won't
turn on unless it turn it down. Is this possible? Its really
complicated to get at the switch cause its embedded into a large
medicine chest, and an old one at that...came with the house.
Sounds like you have a 3way switch and someone accidentally found and
flipped the one at the other end.
