Replacing 2 gang, 2 way light switch

[AlexHUK]

Hi folks,

I'm replacing an unfortunately positioned 2 gang light switch with an equivalent LightwaveRF switch so I can operate it remotely. The sThe left hand switch is linked to another switch at the other end of the room.

Following some advice on this forum I've taken a few photos of the old switch before going any further. I was hoping someone might be able to map out which cables should move to which position on the new switch (eg. 2W(l) in L(l), COM(r) in X(r), etc)

My guess is the 2 xs are the coms the S and Ls are the 1s and 2s.

The OP is asking for advice, not guesses.

Why dosn't he see what the instructions say that came with the switch.

You will not be able to use the two-way switching unless you buy a slave unit to replace the existing two-way switch.

common = L
L2 = lamp
S = slave ( two-way position)

Do not connect L to S or you will damage the dimmer.

If you do not require the two-way ( and are using RF ) you can bridge the 2way switch at the other location and blank it off.

Cheers knowall,

Yes, ideally I'd like to do away with the other single switch altogether and control both sets of lights from the one 2 gang in the photo... I just can't identify which cable comes from that switch, so I thought I'd simply replace the switch like for like.

So based on what your previous post:
COM(r) to L(r)
COM(l) to L(l)

What about:
1W(r) to ?
2W(l) to ?
1W(l) to ?

Thanks,
A

What about:
1W® to = x ®
2W(l) to=x(l)
1W(l) to =x(l)

connecting the blue and yellow together on x(l) will bye pass the two switching.

Remember no connection to S

KFA - that's a dimmer, not a plain switch.

Alex - pay SFA attention to KA - he KFA.

You need a 2-gang slave dimmer at the other location, and you need to understand how your existing switches are wired, and how master/slave dimmers are wired, as they are not the same.

BAS,

If you bother to read all posts, you would know I have explained all of your rant already.

Yeah, right, of course you did

Hi KA,

I finally got round to rewiring the switch following your instructions.

The left switch works fine but the right switch doesn't. The right hand side lights are on permanently. Not sure if I misunderstood something:

The blue and yellow don't go together, did you install a slave switch as mentioned by BAS. You should be aware that knowall, knows less than their name would suggest.
Did you not get installation instruction with this switch? if so they will inform you of the method of installation and the requirements needed to make it function.
