How to Install a Wall Switch

A wall switch controls the flow of electricity to one or more permanent light fixtures or wall outlets.wall switch When it is "on," the switch allows the fixture to be energized; when it is "off," it interrupts the current flow and stops power to the fixture. Wall switches come in a variety of styles and configurations, but all work on the same basic principles. A single-pole toggle switch, for example, features a small squared off device that has words ON and OFF upright on a lever that flips up and down to open and close the circuit. Other devices include the rocker switch, which has a wide rocker arm that snaps up and down to open and close the switch; and push-button switches, which have a single button that turns the fixture on when pushed in and off when pressed again. Some newer switches use microcircuitry to control the flow of electricity and offer programmable or automatic features, or wifi connectivity.

Most light fixture switch boxes are set between 48 and 52 inches above the floor in standard residential construction.wall switch This puts the switches at an unobtrusive height for most people in a standing position, and it also makes it easy for carpenters installing wallboard to cut openings for switch boxes during new home construction. There are no specific electrical codes that dictate the precise height for a light switch box, but most builders and electricians follow routine standards.

There are many factors to consider when choosing where to install a wall switch, including the type of fixture and whether it has multiple switches. If there are two or more switches, it is usually best to place the switches in opposite corners of the room, as this will provide even lighting. It is important to avoid placing a switch by the entrance door, as this will make it difficult for people to reach when entering or exiting the house.

When it comes to replacing an existing switch, the first step is to shut off the power to the switch by turning off the breaker at the main panel. Then remove the old switch from the wall by unscrewing it. Before attempting to disconnect the wires from the switch, it's a good idea to take note of the color of each wire as it is attached to its terminal screw (two are one color, and the third is often green).

Once you have disconnected the wires, carefully mark where each is connected so that you can connect them to the correct terminals on the new switch. Once the new switch is installed, it can be tested by turning it on and off or dimming it to ensure that the switch works properly. Finally, replace the switch cover and wall plate.
