Drill holes as needed in the framing and fish a new cable through the wall back to the old switch position.

Thanks to Acme School of Stuff, I understood three-way. Connect these to the ground terminal on the first switch. Electrically, a typical "3-way" switch is a single pole, double throw SPDT switch. Equipment for new installations is not commonly carried by electrical suppliers, although it is still possible to find parts for maintaining existing installations.

Take the black wire from the other 3 way and connect that to the black wire to the light. That is because now you will hook up indianapolis 'shocked' if you touch the shell while changing the bulb if the fixture is powered, whereas if you had connected the hot from the 3-way switch to the hook fixture's hot side, and if the power were on at the fixture when you change the bulb, the only way you could get shocked is by three the small bare terminal that is all the way inside at the base of the shell.

The bare copper wires tie together with a wire nut. He or she flips the switch to its other position. Wiring a 3-way switch is a little more tricky than wiring a 2-way switch. Grounding switch wires are not counted. Thank you for looking and for commenting. DeanJ14 author Reply I was his helper all through junior high to college. Attach the first wire you unscrew to the same-colored screw on the new hook up des moines as it was on the old; do the same with the second.

I have fixed that. That NFPA regulation will be applicable, in the example above, when the third conductor is three way, and if the hot and neutral from the mains enters the system at a box other than the box at the 3-way switch furthest from the load.

When the left switch is toggled, it connects to the upper circuit and now the circuit is open at the right switch which turns off the light.

The wiring is more complicated than a traditional single-pole switch, but we'll explain how to make the connections. As long as you keep this in mind, a 3-way circuit becomes really simplified. Switches or circuit breakers shall not disconnect the grounded conductor of a circuit. Views Read Edit View history.

In building wiringmultiway switching is the interconnection of two or more electrical switches to control an electrical load often, but not always, lighting from more than one location. Keep the other connections the same, even if you have to disconnect them when you change to a larger box.

The easiest way to do what you want would be to install a remote control in the light.
