Where are two way switches used?
Also asked, what are two way switches used for?
A two way switch is also used as a selector switch to make two different circuits at different times from same supply, or it can be used to select a supply source out of two available for a given circuit.
Similarly, it is asked, where are intermediate switches used?
Intermediate Switches are used for when there are three switches (or more) controlling one light. An example of this could be on a landing, with a switch at the bottom of the stairs, at the top of the stairs and at the end of the landing space.
The one-way switch has two contacts and the two-way switch has three contacts. In a two-way switch, there are two, one-way switches combined in one. One of the terminals can be connected to either of the two, but not both at the same time.
