Wiring Three Way Switches
Electrical Question: I have 3-way switches in the hallway.
- You can turn on the lights at either end separately.
- But if I turn on the light at one end of the hall, then turn it off at the other end – I cannot turn the light back on at the other end, where the switch is already in the “on” position.
- I can turn it back on where I turned it off.
- What’s the solution for me to be able to turn on at the original end, where the switch is at the “on” position already?
