Safely Install Different Light Switches

Light switches certainly have a common appearance within the collective unconscious, but they do in fact are available a spread of types, which vary by style and by functionality.

These tips will allow you to understand the different styles of wall switches and how their installation processes differ from one another.


Working with wall and light switches means working with electricity. Always put your safety first and make sure the ability supply for area you’re engaged on is totally off in order to stop shock injuries.

Normally, all three kinds of switches will be interchanged. Meaning, it doesn’t matter what you currently have installed, you possibly can likely replace with a different type of switch.


Toggle switches are the kind of switch with an arrow-shaped armature that complete the circuit, thus powering the light. When flipped to the “on” position, the armature moves so that the circuit is complete and power can flow to the sunshine. When it is moved to the “off” position, the armature moves in a way that breaks the circuit so that no further current is channeled into the light bulb.


Mercury switches are built with a cylinder that’s partially filled with mercury. The “on” position floods the cylinder with mercury, completing the circuit and powering the sunshine.

Silent Switches

Silent switches are designed in order that a steel spring is the moving mechanism that is switched to open or close the circuit.

Installation Options

The only Pole Toggle Switch

This switch has two brass screws and two wires: a black wire that is the interrupted wire, and a white wire that receives a continuous supply of power.

As you connect the wires, take care that they go in the same direction that the screws tighten in.

If in your switch the wire is alleged to make a connection to the terminal screw before continuing, then you need to apply a 6-inch piece of wire with a stripped end and put all three pieces along with a wire-nut. (Wire-nuts are good for splices.) Be sure to layer sections which were soldered under insulating tape.

The essential rule is to attach white wires to the sunshine attachments and black wires to the dark attachments. Attach ground wires to green screws.

Outside Main Wiring Run

At the light switch, connect the black wire to one terminal and the white wire to the other. Remember, a green screw is always for the ground wire.

In-line Switch to control One Light

To install this type of arrangement, it’s essential to add a 3rd wire, which is usually red in color, from the switch to the outlet where you control it. Set this up once you want to control the first electrical fixture with a switch while the facility continues elsewhere.

Switch and Convenience Outlet in Same Box

Ensure that the facility is off. Attach the pigtail to the brass terminal, and then put a second pigtail onto your choice of terminals at the switch.

Wire-nut these two pigtails and the black wire from the sunshine fixture together. Connect the white wire from the sunshine fixture to the silver terminal on the outlet. Connect the red wire from the light fixture to the opposite terminal on the switch.

At the sunshine fixture, wire-nut the white wires from the power source, the light fixture and the switch together. Wire-nut the black wires from the ability source and the switch together. Wire-nut the red wire from the switch and the black wire from the light fixture together.

Connect the first pigtail to the switch box. Put the second pigtail on the switch of the other box, and connect the wires in line with color code.

How 3-Way Switches Work

A three way switch works slightly different than those already mentioned. The first wire connects the light and the power source. Switches control the flow of power through a second wire. The point where the second wire connects to the primary switch is referred to as the common terminal.

Light Control Beyond the Switches

Connect the white wires with a wire-nut. Likewise, you will connect the black wire from the light to the white wire of the switches.

Working at the first switch, attach the red wire. Connect the black wire to the terminals, and accomplish that with the white wire as well.

Working from the second switch, find the three-way switch and connect the red wire. Connect the white wire from the primary switch to one of many terminals. Connect the black wire to the one remaining fixture. Finally, connect the the black wire of the first switch to the white wire of the sunshine.

Light Control Between Switches

Working at the first switch, locate the common terminal and connect the red wire. Then connect a white wire to a terminal and put a black wire on the only terminal left. Working on the second switch, connect the red wire to the common terminal, and put the white wire to a terminal. Do the same with a the black wire.

Working on the sunshine fixture, it’s essential to first connect the red wires. Then attach the white ones with a wire-nut, as well as with the black wires and the wires connected to the ability source.
