hi all, went to replace a dimmer with a conventional light switch and found this wiring, it's different to what I've seen before (I'm a bit of a novice and can do basic wiring). Anyone able to point me in the right direction as to what wiring i have here? Thanks in advance.

- Red - permanent-live feed from lighting circuit (240V AC)
- Black with red sleeve - switched-live from switch (to luminaire).
- Green - earth to metal backbox.
- Yellow - earth from metal backbox to metal body of dimmer - no longer needed, remove.
A typical UK light switch will have three wiring positions, secured by screws, labelled L1, L2 and L3. L1 will be at one end of the switch, L2 and L3 will be close to each other at the other end.
Connect the red wire to L1 and the red-sleeved black wire to L2.
If you remove the yellow wire (which you should to avoid inadvertent shorts when refitting the frontplate) - I would make sure green is still securely connected to the backbox - this provides an earth to the exposed machine-screws that hold the front-plate.
