How Two-way Switches Work
Two-way switches control one light from two different places. This setup is common in hallways, stairs, and large rooms. It lets you turn the light on or off from either switch.
The switches are connected by wires that carry electricity. Each switch can change the path of the electric current. This change controls whether the light is on or off.
Basic Components Of Two-way Switches
Two-way switches have three terminals. One terminal is the common terminal. The other two are called traveler terminals. Wires connect these terminals between the two switches.
How Electricity Flows In Two-way Switches
Electricity flows through the common terminal. It travels to one of the two traveler terminals. Depending on the switch position, the current reaches the light or stops.
Switch Positions And Light Control
Each switch has two positions. Changing a switch flips the current path. This action either turns the light on or off from either switch.
