New LED dimmer switch

Deregos.

I added an LED dimmer switch to a two way lighting circuit that has six dimmable LED downlights. Both the two way switches worked perfectly fine before, so I exactly copied the wiring sequence from the old standard switch to the new dimmer switch = Com to com, L1 to L1 then L2 to L2. Since I added the dimmer switch, it works okay, but only if the other single standard switch is on. If that standard switch is off, then the dimmer doesn't respond. I tried the swapping L1 and L2 around but that just reversed the single standard switch to act like it's been flipped upside down.

What have I missed or done incorrectly?

Hi ya,

If it's a standard wiring setup with two runners between the original 2-way switches, then that won't work for a dimmer circuit as only one of the runners will be energised and you'll avoid the dimmer when the opposite switch is flipped. See image in this link:

You need to follow this method in "1-WAY, 2-WAY AND 3-WAY CIRCUITS" and the circuit diagrams below instead:

Hope it helps!
