Light Switch On Off Reversed

I have a problem wiring the 3way switches in my hallway.

Light switch on off reversed.

The dimmer is marked up and the has two terminals on the right side plus a wire at the top for ground. The only way to change the orientation of whether it is on or off is by physically reversing the switch. Took picture and my wife double checked 3 black wires on top right. You can reverse the wires and it will work exactly the same way.

Forgive my ignorance is this a case of face plate being put on upside down or are they wired wrong. If the lamp only lights on one terminal the switch is either broken or needs adjusting. I have two 3way switches in the hallway. The black wire is the hot wire the one you should never touch with the power on.

Replace the switch in reverse order then. No matter how i install the wires the switch always tuns off in wrong position. Fourth this is in fact the way the switch has always worked. If this is the case perhaps the other switch is seldom used and it has been used once and effectively reversed the switch you commonly use.

If it is a single pole and not a decora style it should have on and off printed on it and would be impossible to reverse the function. Look at the switch. If the lamp fails to light at all check the wiring between the fuse and switch. It dims the cree led bulbs great.

Off is on on is off. Wiring 3way switches electrical question. Next never do any wiring unless you c. There is just one problem.

Went to home depot and bought new dimmer boucht cfl compatible dimmer as tried cfl floods before and they only lasted a few weeks hooked up same way as before. Either switch can turn the light on or off. To replace a reversing light switch disconnect the wiring and either unscrew the switch or if a locknut is used release this. Dimmer in kitchen 5 dimmable flood lights went out.

You can turn on the lights at either end separately. I have a number of light switches in my house that are reversed i e. A light switch is a single pole switch. If i turn on the light at one end of the hall then turn it off at the other end i cannot turn the light back on at the other end where the switch is already in the on position.

Never touch any wire with the power on and use a meter to double check they are all off before touching anything.
