You email bounces as unknown?
I believe if you call the local hardware store, they should stock
something called a 4-way switch. (don't hold me accountable for the name
but I believe that's what it's called)
it has 4 contacts on the back and needs to be used with two 3-way
switches. There can be as many 4-ways switches added to the circuit as
wanted so you could have 50 switches all controlling the single light if
The 4 contacts (2 pairs of 2) reverse connections to each other when the
switch is flipped. iIn a typical 3-way circuit, there are two wires run
between the 3-way switches. You can 'splice' a 4-way onto these 2 wires
or 2 or 3 or 4 or 5, etc...
A 3-way circuit routes the 'live' connection thru one of these 2 wires
and each 3-way switch need to be on the same 'live' wire for the light to
operate. The 4-way switches switch which of the two wires is 'live'.
I hope this makes sense, it would be much easier to draw!
