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 controls the state of an SPDT (single pole double throw) switch. Each switch is wired to all of these switches and are wired up to control a light bulb. Basically when you close the switch, it sends current to the wires controlling the light bulb. If any of the switches are off, it closes the wire, allowing current to flow and turn on the light.
I can try to make a circuit diagram of this if it’s confusing.
But basically if any of the switches are on, it ceases the loop and the light doesn’t turn on.
