What is 1 way and 2 way switch?
1 way is an on/off switch and means theres only one place you can turn your light on or off. This is the most common kind of switch found in most homes. Most 2 way switches can also be used as a 1 way on/off switch. 2 way means theres another switch controlling the same light.
How does a 2 way switch work?
Two way light switching works by having two wires in between the two different switches. What these two wires do is that they act as an alternate bridge point between the switches that allow them to connect the circuit to the light source from either switch.
