Help Rqd - Changing light switch

[jaybee69]

Hi All

Not an electrician, just do little diy jobs!

In the lounge we have wall lights & a centre light.

Currently has an 'ordinary' switch. (2 switches on the same 'plate')

Want to fit a dimmer switch

The box contains 3 twin & earth cables

The 3 neutral wires are connected together.

3 red wires...
1 goes to L1 on one 'switch'
1 goes to L1 on the other 'switch'
the 3rd red wire goes to common on one switch, with a 'link' to the common on the other 'switch'


First off...Is the original wiring correct?

And the real question...Can I change this to a twin dimmer switch?
Will there not be some 'interference' between the 2 circuits since they are sharing 'one side'

Many Thanks

The wiring is perfectly normal.

Yes you can simply switch to a 2 gang dimmer. Wiring will be exactly the same. I believe wiring diagrams for lights are on the wiki.
