A 2 way switch is a fundamental component in electrical wiring that allows you to control a single light or electrical device from two different locations. This type of switch is commonly used in stairways, hallways, and large rooms where multiple entry points require control over the same light fixture. The 2 way switch has three terminals, which are typically labeled as common, L1, and L2. The common terminal is the point where the power source is connected, while the L1 and L2 terminals are the traveler wires that carry the electrical current to and from the switch. When the switch is in one position, the L1 terminal is connected to the common terminal, and when it is in the other position, the L2 terminal is connected to the common terminal. This allows for the control of the electrical circuit from two different locations.
In order to understand how a 2 way switch works, it’s important to grasp the concept of a single pole switch. A single pole switch is the most basic type of switch and is used to control a light or electrical device from a single location. It has two terminals, one for the incoming hot wire and one for the outgoing hot wire. When the switch is in the on position, the circuit is closed, allowing electricity to flow to the light or device. When the switch is in the off position, the circuit is open, cutting off the flow of electricity. A 2 way switch essentially combines two single pole switches into one unit, allowing for control from two different locations. This is achieved through the use of traveler wires that connect the two switches and allow them to communicate with each other, effectively creating a circuit that can be controlled from multiple points.
