3 way switch wiring diagram The above 3 way switch wiring diagram shows a typical 3 way switch installation. The top 3 way diagram shows the light switches installed and wired to control one light from two locations. In electrical renovation you may want to change from a 3 way switch control to a single switch control. The botton wiring diagram shows you how to abandon the first 3 way switch and change to a single light switch control. Basicaly, all you have to do is tie the blacks together in the first box and abandon the red traveler wire. Then in box 2 use the black with a single pole light switch and again, abandon the red traveler wire. Alway turn of power before attempting to perform any electrical work.

Motor Control Curciut The motor control circuit diagram above shows a typical control scheme with a start stop push button and control relay. The indication lights are operated from the aux contacts of the motor starter to show running or stopped. The control relay circuit handles the latching of the contracts so the 2 and 3 aux contacts on the motor starter are unused.

Switched Receptacle option 2 The wiring diagram above shows one method of wiring a switch receptacle. The 20 amp feeder is ran to the receptacle first then a switch wire is ran from the rec box to the switch box. When using this method you have to use the white (neutral) wire as the switch wire, use black electrical tape to mark the white wire to indicate it is being used as a switch wire. If you are feeding the receptacle with a 20 amp breaker make sure to use a switch rated at 20 amps also. As always, turn off all power and verify before doing any work.

Switched electrical outlet diagram. The wiring diagram about shows the receptacles being controled by switch. Remember that the typical light swich is rated for 15 amps, you can get heavy duty switchs that are higher rated for this application. I recommend only switching a single receptacle so you dont overload the switch. As always, before doing any electrical work turn off the power and verify.
