Dimmer switch qustion

[David123]

I am trying to replace a dual on/off switch with a dual dimmer switch (one way switching) that controls a separate wall and ceiling light.

The existing switch (on/off type) has the following connectors: B(COM); A2; A1; B2; B1; A(COM). The wires are connected as follows:
(1) Red wire -> A then second red wire -> B (COM)
(2) Blue wire -> B2
(3) Yellow wire ->A2
A1 and B1 connectors unused.
Earth wire to earth

The new switch I wish to use has 2 sets of connectors, each with L1; L2;~arrow through signage.

Some advice on the correct rewiring from the on/off to dimmer switch would be greatly appreciated

Each section of the old switch was
(com) A .. A1 A2

(com) B .. B1 B2

On the dimmer side one
use cable A (com) red into L1
use cable A2 yellow into ~

On the dimmer side two
use cable B (com) red into L1
use cable B2 blue into ~

If the reds are not linked together and are seperate
MAKE SURE YOU MARK them
and get the
A red paired up with the A2 yellow (via one side of dimmer)
and
B red paired up with the B2 blue (via other side of dimmer)

Dear Rocky

Many thanks for the advice, I'll give it a go.

Just to be clear, I run the cable red wire into L1. Then connect a separate red wire between L1 dimmer side one and L2 dimmer side 2?

Have a look on the Wiki first.

NO just use the wires you have
NO EXTRA
The L2 terms are not used
sometimes there is ALREADY a red link IF THERE IS NOT it does not apply to you

If the TWO REDS were not linked YOU NEED to mark them as said, as they ( THE INPUTS) are paired up via the switch with the relevant ( LIGHT OUTPUTS)
In your case it was A and A2 ********* B and B2
