UK lightswitch swap from dimmer to switch help!

[slinkie172]

Hi all,

I have a dual dimmer switch in my living room for 2 ceiling lights. I am using LED light bulbs and so the dimmers don't work without the lights flickering so I wanted to change the switch to just a normal on off switch. I removed the old dimmer, wired in the new switch in the same way the other switch was wired and now I am having an issue with one light that refuses to turn off. On the picture it would be the light associated with the switch on the right. Any ideas on why this would be? The dimmer switch worked ok like this. the below is a crude paint sketch of the wiring in the back.

If you haven't got the L22 wire and the common wire mixed up then the diagram shown above looks correct.

Which LED lights do you have?
How bright is the light when turned off? A lot of the time LED's can remain lit when the switch is in the off position.

Buy decent LED bulbs that know how to dim; Google for Philips WarmGlow, Megaman Dim To Warm or similar LED that mimic halogen (the light they emit becomes redder as it dims, which creates warmth to the tone) - if you get basic dimmable LED they're weird: they stay the same colour but get less bright, like turning the brightness down on the TV; everything just goes kinda grey

Why do you need the link wire from COM 1 to COM2?

The light is on, not dimmed or partially on. It is 100% on.

We never used dimmed lights which is why i am changing the switches rather than the bulbs. Even pre LED lights we only ever used on or off.
