Simple switch or in and out : electrical diagram wiring and installation

The setting up and connection of a single or two-way switch are undoubtedly among the most basic tasks that every amateur electrician must know how to master. This small work of electricity is perfectly accessible to each one of us. Follow the instructions.

Choosing the right switch

First, here are some tips for selecting the right model of switch. Indeed, with the many models available on the market to name only the back and forth, the rocker model, or even dual ignition, you can quickly get lost.

But already used to turn off and on, the single switch is the easiest to install. However, many criteria will have to be taken into account when purchasing it. Is it for indoor or outdoor use? For certain rooms subject to humidity such as the kitchen and the bathroom, bipolar models will be preferred. Otherwise, if you plan to install the electrical appliance yourself, prefer a ready-to-install switch to the ranges to be assembled and built-in.

Place the switch correctly

The first step is to define the location of the new switch, more precisely its height. And according to the standards in force, this electrical equipment must be 90 centimeters from the ground minimum and 1.30 meters maximum. As a result, the switch is at the same time within the reach of adults, children and adolescents. Also, for ease of access, it is best to place the single switch at the entrance to the room, not far from the door.

Tools needed to install the switch

In addition, some tools will be necessary for the accomplishment of this small craft, namely: cutting pliers, stripping pliers, Phillips and flat screwdrivers, the switch, electrical wires and a flush-mounting box. Furthermore, no manipulation is possible if the incoming current is not completely cut off. Otherwise, you risk serious electrocution, even death.

Switch connection

Since you are installing a new switch, you must first create new electrical wiring on the existing circuit. The next phase is the connection of the switch. Using the cutting pliers, strip the two red and blue wires that you will then connect to the terminals of the electrical equipment. Place the switch in the flush-mounting box, fixing it securely with screws. Afterwards, you can finally proceed with the assembly of its facade. Turn the power back on and try the switch. It should work!
