Is 2 way and 3-way switch the same?
Much like the two-way switch, a three-way switch turns a light on or off. However, there is a crucial difference. The three-way switch is used in conjunction with another three-way switch. Each one of them has the power to interrupt the electrical flow and turn the light off from a different part of the room.
Can I use a 4way switch as a 3way?
A 4way switch will not work in place of a 3way. The common toggle (in), whether up or down on a 3way switch, comes in contact with both switch leg (out) terminals. A 4way switch will not accomplish this. The 4way is more like two “separate” single gang switches, they will not work in unison as one.

How many switches do you need to construct a three-way switch circuit?
A 3-way switch circuit is always comprised of two 3-way switches that control light(s) or device(s) from two different locations.
What is a 3 way switch called?
single pole, double throw (SPDT)
Electrically, a typical “3-way” switch is a single pole, double throw (SPDT) switch. By correctly connecting two of these switches together, toggling either switch changes the state of the load from off to on, or vice versa.
