Black wire power or hot wire. 2 way light switches are helpful to turn on or turn off light from different end locations.
Ceiling Fan Switch Wiring Electrical 101
Two way switch function. A 2 way switching connection means you can control an electrical equipment like bulb by two switches placed at different places generally used in the staircase. A two way light switch is a simple single pole changeover switch with three terminals. Two way electrical switch means one way switches combined into one. The neutral in this sketch is the black wire. What is referred to as a two way switch is typically used to switch a light from two locations such as opposite ends of a hall. Making onoff light from two end is more comfortable when we consider stair case two way light control is simple and easy to construct.
In position 1 when the switch is down or on com and l1 are connected together just like the one way switch. In the other switch position it changes over so that com is connected to l2. Each of the gangs or switches above in fig 2 of which there are two work like this fig 3. In this article simple two way light switch connection described with neat circuit diagram and wiring details. Hello two way switching is used to operate a lamp or device from two locations in the example below the power from the fuse bypasses s2 and continues to s1 the through the made solid line back to s2 then through the made solid line to the light. The switch terminology reflects on how each type of switch functions.
When one connection is made the other gets damaged or broken automatically. In position 2 when the switch is up or off com and l2 are connected together. Two way switch can be operated from any of the switch independently means whatever be the position of other switch onoff you can control the light with other switch. But keep in mind one of the terminals gets merged to any of the switch but not both at a time. In this way breakage can be occurred. These are typically labelled com l1 and l2 some may label the l1 and l2 positions as 1 way and 2 way.
When wiring a 2 way switch circuit all youre really doing is controlling the power flow switching offon to the load a light lamp outlet ceiling fan etc now a typical circuit will contain a 3 wire cable known as romex. In such a situation a two way switch is put in a switch box at. The cable consist of a black wire a white wire and a bare copper wire. A 2 way switch simply means you are controlling 1 wire in 1 wire out spst single pole single throwbr a 3 way switch is 1 wire in 2 wires out or spdt single pole double throwbr a 4 way switch is 2 wires in 2 wires out or dpdt. In one switch position the com terminal is connected to l1.
