Two Way Switching Explained - How to wire 2 way light switch

This video tutorial covers the theory of controlling a light with two switches, emphasizing safety and the need for qualified individuals to perform electrical work. It explains the differences between three-way and two-way switches, their terminals, and how to wire them to control a light. The tutorial also demonstrates converting a one-way switch to a two-way switch and explores alternative wiring methods. Throughout, the importance of using brown sleeves to indicate intermittently live wires is highlighted.

What is the main difference in terminology for two-way switches between the US and the EU?

• The US calls them two-way switches, while the EU calls them three-way switches.

• The US calls them three-way switches, while the EU calls them two-way switches.

• Both the US and the EU call them two-way switches.

• Both the US and the EU call them three-way switches.

What happens when you flip one of the two switches in a two-way switch setup?

• The circuit remains unchanged, and the light stays in its current state.

• The circuit can either be completed or broken, depending on the position of the other switch.

• The circuit is always completed, and the light turns on.

• The circuit is always broken, and the light turns off.

What is the first step in converting a one-way switch to a two-way switch?

• Connect the live wire to the common terminal of switch two.

• Run a black wire between the two common terminals.

• Connect the live wire directly to the lamp.

• Cut the live wire feeding the lamp and run it into terminal L1 of switch one.

Which wire is used to connect the two common terminals in the conversion method?

• Blue wire

• Black wire

• Gray wire

• Brown wire

In the alternative wiring method, what color wire is used to connect L2 of switch two to L1 of switch one?

• Brown

• Gray

• Black

• Blue

What is the purpose of placing a brown sleeve on the wires?

• To warn that the wire is intermittently live.

• To indicate that the wire is a neutral wire.

• To mark the wire as a common wire.

• To indicate that the wire is a ground wire.

In the fourth variation, which wire is connected between the two L1 terminals of both switches?

• Blue wire

• Black wire

• Gray wire

• Brown wire
