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.
Thanks for your help I have fixed it myself 2 blacks to loop 1 red to
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
