I’m changing light switches to decora from toggle.

I have 4 switches to one light fixture where 4 of the 3 switches have 5 wires and the 4th switch has 3.

  • 1: 2 red 2 black 1 ground
  • 2: 2 red 2 black 1 ground
  • 3: 2 red 2 white 1 ground
  • 4: 1 red 2 black 1 ground

If a 5 way requires 2 4 way switches and 2 3 way switches - which gets 4 way switch? What do I do with the extra wire on the switch were I put a 3 way decora?

    Welcome to StackExchange. This information could have several meanings, especially in the 1st and 4th switch. What we need is photos of the wiring. Wire color is essentially meaningless in 3/4 way wiring, but pay very close attention to screw color. – Harper Sep 5 '18 at 3:58

    Can you post photos of the insides of the switch boxes? – ThreePhaseEel Sep 5 '18 at 4:01
  • I'm a little confused by your descriptions: I have 4 switches to one light fixture where 4 of the 3 switches Do you mean 3 of the 4 switches? And then you go on: If a 5 way requires 2 4 way switches and 2 3 way switches A five-way system requires five switches - you list only four. – mike65535 Sep 5 '18 at 13:43
  • There is still a switch to find, unless it was previously removed from the circuit. In standard multiway switched, each “end” will be a 3-way, and all the switches in between will be 4-way. If you have an extra wire where you want to put the Decora switch, then you bought the wrong switch, you need a Decora 4-way, not 3-way. – Tyson Sep 5 '18 at 14:32
  • @Tyson we can't say that, because we don't know what the 2 blacks are doing in switch 1. It's entirely possible both blacks go to the same 3-way common, and one is simply carrying power onward to another switch or load. – Harper Sep 5 '18 at 15:55
