How To Wire A Switch In Series

The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer remote control or other programmable switch.

How to wire a switch in series. Wiring a switch in series because the purpose of a switch is to interrupt the hot leg of the circuit when it s off it has to be wired in series and for this reason it has only brass terminals and a ground. A light switch is the switch that we position within the switch boards for the purpose of switching on and off the lights. Instead of running a separate pigtail from the hot wire to each switch just leave the hot wire extra long. Because the electrical code as of the 2011 nec update requires a neutral wire in most new switch boxes a 3 wire cable runs between the light and switch.

Another major defect of series lighting circuit is that as all lamps or bulbs are connected between line l and neutral n accordingly if one of the light bulb gets faulty the rest of the circuit will not work as the circuit will be open as shown in fig below. A one way light switch has two terminals which is a common marked as com or c. The terminals are brass. Finally screw the ground or green wire to the metal screw in the box.

For wiring of 2 lights with one way switch or controlling two lights in series by switch first of all connect the neutral wire to first terminal of light bulb socket lamp holder and then connect a wire between lights sockets as shown in below diagram. Connect the end of the hot black wire to the brass terminal. Step 5 wire the series. A switch interrupts the hot leg of the circuit so it has terminals only for black wires and ground.

The other terminal is marked as l1 and is the output to the light fixture. Connect the last switch in the usual manner looping the wire around the screw in a clockwise direction. Mostly this is not a proffered method to wire single way switches in series as parallel or series parallel connection is used in common electrical wiring installation. Here you can see there is a cut in the line wire connected to lamp 3 so the bulb is switch off and the rest circuit is working.

In the first outlet box strip inch of the insulation off the ends of the wire you ve just run. This serves to be an ideal ways of dealing with the wire circuit and if we make the wrong wiring connection the entire wiring may meet fire when you switch it on and thus you have to keep all the depending factors in mind while you locate the switch wiring and make the. The common is for the live wire that supplies the input voltage to the switch. In some case it may seems useless connection but there are some possibilities where we have to control single load from two places while both switches must be switch on to operate the load.

You connect the black wire from the power source to one of these brass terminals the line terminal and the black wire going to the light fixture to the other which is the load terminal. To connect the switches simply score the wire with your wire stripper and push the insulation to expose about 3 4 in.
