Two Way Electrical Switch Wiring Diagram
Let s assume the load you are controlling is a light. In position 2 when the switch is up or off com and l2 are connected together.
Wiring Diagram For 3 Way Switch Http Bookingritzcarlton Info Wiring Diagram For 3 Way Switch Light Switch Wiring 3 Way Switch Wiring Electrical Wiring
The schematic shows that the circuit is complete and the bulb is on.
Two way electrical switch wiring diagram. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light. The source is at sw1 and 2 wire cable runs from there to the fixtures. Suppose you want to turn off the bulb top of the staircase from the upper switch above the ladder then switch off the switch then the circuit will break and the bulb will close.
A 2 way switch wiring diagram with power feed from the switch light. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. This diagram illustrates wiring for one switch to control 2 or more lights.
2 gang 2 way light switch wiring diagram uk. This method is commonly used nowadays as it is efficient than the two wire control system. The one way single pole two way double pole are the two types of an electrical.
The next length of the twinearth cable will run from the light to the first two way switch. To switch from two locations youll need 2 two way switches and wire them together in a particular way. This is a completed circuit.
As the diagram at electrical 101 shows the line cable is all you need to supply power to a pair of switches in a single electrical box. How to wire 2 way light switch in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches. Consider the 2 way switch wiring diagram above that is used to control the bulb in the stairwell.
You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light. After making sure the power is off you strip the black wire in the two conductor cable which also has a ground wire and make a pigtail with two 6 inch lengths of black wire salvaged from a spare piece of cable of the same wire gauge. Pin1 of both the switches are connected with the phase or live wire and pin2 of both the switches are connected with the one end of the lamp.
The electricity flows from the hot wire black through the 2 way switch shown in off position and then to the light and returns through the neutral wire white. As you can see in the schematic diagram of 2 way switch circuit below the common of both the switches are short circuited. The power source comes from the fixture and then connects to the power terminal.
This is the new method to make a 2 way switch connection and it is slightly different from the two wire control method.
