This is a completed circuit. If a light switch is 1 way this means it is just an onoff switch.
3 Way Switches Electrical 101
What is a 2 way light switch. 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. Wiring two switches to one light fixture adds convenience to any room with two entryways. Before proceeding an important component called a two way light switch is the main element of the 2 way switching irrespective of the type of wiring used. Its okay if this is too complex for you. 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. 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.
So what is a 2 way switch. This practice maintains the loop form when the terminal screw is tightened. When attaching the looped wires to the switches keep the open end of the loop to the right. The third wire creates repetitive switching at either end. A two way light switch produces light when two of three wires transport a current to either end of the installation. It is a standard single pole switch with three terminals.
By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. A two way light switch is a switch that can be used in conjunction with another two way light switch to turn a light or lights on and off from more than one location. The red wire is the traveler that carries the current from one switch to another. The 2 way switch or single pole double throw switch is a three terminal switch. Because it uses two switches and one appliance. So why is it called a 3 way switch.
Now lets look at the 3 way switch. Well break it down pretty soon. There are 3 basic types of switches that are used for domestic purposes. This is the simplest type of switch. A light fixture can operate with two switches in different locations. The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used.
Here 1 terminal is the input and the other two are used as outputs. Lets assume the load you are controlling is a light. A 2 way switch means there is another switch controlling the same light.
