By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. Two way switch lighting circuit diagrams.
Corridor Wiring Circuit Hallway Wiring Using Spdt Switches
Two way switch diagram. The schematic shows that the circuit is complete and the bulb is on. As you can see in the schematic diagram of 2 way switch circuit below the common of both the switches are short circuited. 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. In the above diagram the black core of the 3e has been connected to the com terminal and the brown to l1 and the grey to l2. 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. Here is our selection of two way switch circuit diagrams.
This is a completed circuit. A 2 way switch wiring diagram with power feed from the switch light. Two way switches usually have terminals marked com l1 and l2. Alternative method of two way switching. Lets assume the load you are controlling is a light. The electrical symbol indicates where power enters the circuit.
Consider the 2 way switch wiring diagram above that is used to control the bulb in the stairwell. The other end of the lamp is connected with neutral line of ac power supply. 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. Do you need to know how a two way switch works before you check out the circuit diagrams. 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 power source comes from the fixture and then connects to the power terminal.
If you need to know how to wire a two way switch then this is the place to start.
