2 Way Switch 2 Lights. Two way switch can be operated from any of the switch independently, means whatever be the position of other switch(ON/OFF), you can control the light with other switch. The next part is where i have added two way switch to the relay and light setup.
A light or lights can be controlled by more than one switch.
Here are step by step instructions on how to wire up a two way lighting circuit or to change a existing one way light switch to a two way system, this is very useful on stairs etc. as you can have a switch at the bottom and the top of the stairs.
These two way switches have a single pole double throw (SPDT) configuration. If you have one light switch that turns your light on and off, then that's a single-pole light switch. That's different from three-way light switches, which you might find in large room or a room with several entrances, where the main light in the middle of the room can be switched on and off by two.
