I am trying to replace a light switch and have removed the old switch
and am having troubles deciding where the 4 wires go on the back of the
new switch.I have 2 red & 2 black The back of the switch has 4 holes.
One at the top has a plastic cross over it & I suppose that means I
don't use it To the right it says common to the left it says loop & the
last on on the bottom in the middle is unmarked.
The existing wires seem to want to go as follows; 2 black are together
& want to be on the left (loop) I think.
I guess the 2 reds are the switch wires.Am I correct in thinking 1 goes
to common & the other to the unmarked bottom
Is this a 4-way light switch? (that is, is it one of more than two
switches that control the same light?) I'm guessing yes, from your
description. It also sounds like you've purchased a 3-way as a
replacement; that won't work.
replace "fly" with "com" to reply.
Thanks I did actually note their original location but they came apart
in the transfer.
It can't be that complicated active & neutral in active &
neutral out through a switch
keep the 2 neutral together & the 2 reds thru the switch to break the
circuit.I'll go with that.
It was only the back of the new switch that stumped me.I'll work it out
I just went & bought another archetrave switch to check to poles on the
back & yes they have 4 places for the wires
Were the 2 reds or maybe the 2 blacks connected to the same screw when
before you took out the old switch? Make a sketch of the old switch
wiring right now, when you still might remember what it looked like.
Ignore my first question and make the sketch like you remember it.
common 1 red to other on bottom & surprise surprise it works.I just got
a bit scared & confused when they came apart.It was only a matter of
working my way thru it .the extra hole confused the issue.
Thanks for your time.
Alls well that ends well
