I have three switches that control the same for your light, I would like to keep two one of the top and bottom of the stairs and eliminate one in the middle. Is there a way to connect the wires in that switch box to eliminate the third switch

    Cut the power, pull the switches from their boxes, do NOT disconnect any of the wiring and provide pictures of all the wiring. Someone will be able to tell you how to connect things up.

    Yes this can be done but we need to know the wiring, normally you will have 2 3 way switches and 1 , 4 way. Depending on how it’s wired will dictate what is done to bypass the switch. If a 3 way connecting 2 of the wires together and capping the 3rd. A 4 way the travelers in and out are spliced together for A then B so 2 splices the ground removed from the switch and a blank cover installed. Not much to it but we need to see how it is wired to provide specifics

    Where exactly is the switch you want to remove? It might be required by code.

First of all, one of those three switches is a 4-way, or nothing would work.

The sequence is: mains power --> 3-way --> 4-way --> 3-way --> light fixtures.

Whereas a 3-way flips which of two 'out' leads is connected to the single side, the 4-way flips the two incoming leads so that each is connected to one or the other of the two outgoing leads.

So, if your undesired switch is the 4-way, you merely need to tie the two incoming leads to the two outgoing leads. If your undesired switch is the 3-way feeding the light fixtures, then tie the two incoming leads to the single outgoing lead. Similarly, if you are removing the first 3-way, connect the incoming mains power to ONE of the leads. Cap off the other lead there and at the box containing the 4way (you could replace the 4way with a 3-way but so far as I know that's not required by code).


One thing you should consider is that extra switches are typically not added for convenience and they are usually required by code. I can't cite all of the rules where code requires switches, but its typically at each entrance to a room, and at the top and bottom of the stairs.

You didn't explain exactly how you have a switch in the middle of the stairs, but if there is a landing that leads to a room in the middle, that switch is required.

There is a chance that a remodel has actually rendered a switch totally useless and in some cases removal is an option, but most of the time someone "never uses that switch" and wants to remove it even though it has a legitimate use.
