# What is Two way Light Switch?

Two way light switch means controlling single light or electric device by using two different switches from different locations. Here each switch will have common terminal, L1 and L2 (L = Line terminal). By using electrical wire 2 switch terminals are connected. Here after electrical circuit completes when both two switch ON or two switch OFF. If either one switch becomes ON or OFF means electrical circuit will not complete between switches and light hence there will no current flow. Use electrical switch depends on your electrical specifications. Always remember two way switch will have three terminals.

# How Two Way Switch Works?

2 way light switches are helpful to turn ON or turn OFF light from different end locations. In this article simple Two way Light Switch Connection described with neat circuit diagram and wiring details.

Making ON/OFF light from two end is more comfortable when we consider stair case, two way light control is simple and easy to construct.

Wiring diagram for Two way light

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. Way terminals of each switch  is connected with each other, Neutral line is directly connected to the lamp load.

Stair Case Light wiring

Two way light control is mostly used in stair case light application. Two switches are placed near to stairs at two end, when we turn ON/OFF the switch at any end the light present state changes to opposite state, if light presents in ON condition then it becomes OFF, if light present in OFF condition then it becomes ON.

By this animation you can understand the operation of two way light.

Note: This circuit involved in handling of high AC Voltage, So handle with extreme care, caution and protection.
