How does an electric circuit work where there are multiple switches? One light circuit in my house has four switches; three along a hallway and one downstairs. Using any switch either turns on all the lights or turns them all off regardless of other switches positions.
In: 4
Each switch switches between 2 lines
Switch 1 chooses whether your input goes to Line 1 or Line 2
Say switch 1 is powering Line 2
Switch 2 chooses which Line to pull power from
So if switch 2 is pulling from line 2 it will get the power that switch 1 is giving it, but if it pulls from line 1, there’s nothing giving it power
And it’s the same concept if switch 1 powers line 1
