Wiring a 3-Way Light Switch. A three-way wall switch is a common type of light switch that makes it possible to control a ceiling light or other electrical fixture from two different locations in a room. But the out point is L1 of the switch1. There are single pole switches controlling things from a single location, three-way switches controlling lights or outlets from two locations, and for larger homes or complicated situations, a four-way switch may be used to control lighting or outlets from three or more locations. You can see in the schematic that Neutral is connected to light, while the other terminal of the light bulb is connected to the common of switch 2. The other is not. Light type. In the double switch I have the single live in L1 and the 2 neutrals in L2. Still, the one-way switch is the most commonly used switch in homes and in many applications where you want to control the flow of electricity. Just from the name, we can assume that these switches are different. A four-way switch has an extra common screw to bring the total number of screws up to four: two common screws and two brass screws (not counting the ground screw). The switch is on when the COM terminal and L, There are three types of circuits they are open circuit, close circuit, and short circuit. Now, take a live wire and connect it to the common terminal of switch1 (left hand side) and take another wire from common terminal of the switch2 (right hand side) and connect it to a lamp. Basically, it has a common contact and can select one of two other contacts. A common(C), L1 and L2. Users must know how wires cross and work together to create simultaneous lighting. In between the two switches, the two lines are called, . 4 and 5 – both permenantly live conductors. CTRL + SPACE for auto-complete. The two-wire control two-way switch is shown in the below figure. A 1 gang switch will control a single lighting circuit, and with a 2 gang switch you can control two lighting circuits, and so on.
