2 Gang 2 way but only for 1witch!

[Goten_151]

Right all, thanks for taking time to look at this!

What i currently have here is a 2 gang? (i.e. 2 seperate switches in 1 box)

the one switch turns on 2 flourescent tubes down one end of the attic, the other turns on the other 2 down the opposite end!

current setup is

all 3 blacks are joined,
red feed into common, which is crossed to the other common
red feed out from L1
red feed out from L1(2nd switch)

Soooooo, i have a live cable coming in and the other 2 run off to the lights.

what i want to do is make ONE of the switches into a 2 way, the wiring is in place as is the new switch.

i tried plenty of combinations, some work but trip the switch when the lights are turned off?!

Any help would be MUCH MUCH appreciated!!!!

Thanks again!

Dave

see the wikki for 2-way light circuits.

Very quick sketch.

Leave the black neutrals in the block at the back of the switch - do not ever attempt to place these neutrals into the switching circuit - this WILL cause your breaker to trip when turning on or off due to a SHORT CIRCUIT which can damage your switch, mcb and ultimately your wiring and yourself!

Will try as soon as i get home, though i'm sure i've done this already!

Will let you know!

Works a treat! Many thanks!

I wasnt far off the solution, i DID follow the wiki which shows red & blue in L2 & yellow & BLACK in L1, so as you know that didnt help in this case lol

thanks again
Dave!
