How To Wire A Switch To A Light Bulb

The following simple wiring diagram shows that how to wire a pilot neon light switch with a lighting point.

How to wire a switch to a light bulb. Disconnect all screw connections and wire nut connections and remove all the wires the main lamp cord running down through the base of the lamp and the two shorter cords leading to the sockets. Wiring a 2 way neon pilot light switch with light bulb. If there is no existing light bulb or fitting just loose wires skip this step and proceed to step four. Remove the existing light bulb and fitting.

There s a much greater potential for getting a dangerous shock especially when changing a bulb. And when the switch is on only the tab at the bottom of the socket is hot but if the wiring is reversed and the power goes to the threaded socket the threaded socket is always hot whether the switch is on or off. The most common requirement of any hardwired automated light switch is a neutral wire. For those of us using led fluorescent or some other energy efficient bulbs under 20w a neutral is required.

Connect the source wire to the bottom terminal of the switch and the other black wire to the top terminal. Remove the light bulb by hand and the fitting by screwdriver. Here you can see that the line connected to lamp 3 has a cut in the wire so the bulb switch is off and the rest of the circuit is working properly i e. The l2 terminal is unused.

Yes there are a few read very very very few switches that don t require a neutral but those will limit you to incandescent only. The bulb is. 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. As each lamp or bulb is connected separately between line l and neutral n if one light bulb is defective the rest of the circuit will function smoothly as shown in fig below.

The wiring diagram clearly shows that the live line or hot wire is connected to on the black terminal on line side. Then pop the outer shells off the bulb sockets exposing the inner metal socket and the wire connections. A two way light switch can also be used in in place of a one way light switch in this instance the red wire from the feed cable is connected to the common c terminal and the red wire going to the light is connected to the l1 terminal. In this picture you can see the strip gauge on the back of the 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. Simply strip the wire to the length specified and push the wire into the hole.
