Two way switching connection is used to control electrical appliances and equipment like fan lighting points etc from different places by using 2 way switches. The circuit of controlling lamp from two way switch is simple in this connection we use two way switches for this first of all connect the neutral wire to the lamp or bulb socket and then connect the phase or line wire to the common terminal of the first two way switch the do connection between the other terminals of first and 2nd switch.
Three Way Lights How Three Way Switches Work Howstuffworks
Two way switch connection with lamp. The most common use of 2 way switching connection is staircase wiring where a light point can be controlled from two three or even many locations. Notice the black wire is the only wire that we are controlling through the 2 way switch. 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. Both the standard and alternative variations can be configured as a carter system. Way terminals of each switch is connected with each other neutral line is directly connected to the lamp load. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2 way switch and a black wire from the other screw on the 2 way switch going to the load light ceiling fan etc.
To construct this setup we need 2 two way switches here common terminal on one switch is connected with phase line and another switch common terminal connected to the lamp load always prefer switch connection in the phase line. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. Two way switch can be operated from any of the switch independently means whatever be the position of other switchonoff you can control the light with other switch. Power is fed to the circuit in the same way however the lamp is connected between the com terminals of the pair of two way switches. They are wired so that operation of either.
Wiring a 3 way light switch. 2 way switch 3 wire system new harmonised cable colours 2 way switching means having two or more switches in different locations to control one lamp. Thus depending on the switch settings the lamp can see either 2 neutrals 2 lines or one of each.
