I've posted this before but see post 'have i bought the wrong
switches'


i have now reconfigured the wiring. to summarise i have a main light
(2 way single) switch next to my door and a wall switch (two way
double) which controls the main light from another location and also a
completely seperate set of light. I will describe how everything is
wired below .Everything works ok apart from the fact that when the
main switch is on and therefore the main light is on; the switch which
should switch it off/on (on the double switch) does not work. as a
point to note if the main switch is off the secondary switch on the
double switch does switch the main light on/off with no problems. fyi
the other switch on the double controls a wall light which works as it
should. to summarise i need to be able to switch the main light on and
off from the double switch when the light is already switched on at
the main.


heres the wiring at the main single switch which controls the main
bedroom light


L1 - BLACK AND BLUE
COMMON - RED
L2 - RED AND YELLOW


THE CABLE WHICH CONTAINS THE RED AND BLACK CABLE FYI THIS IS RED WIRE
WHICH IS IN COMMON


************************************************** ************************************************** ***********


HERE IS THE WIRING IN THE DOUBLE SWITCH


L1 - YELLOW
COMMON - RED TERMINAL BLOCK 1
L2 - BLUE


COMMON - RED TERMINAL BLOCK 2
L2 BLACK


TERMINAL 2 CONTAINS BOTH THE BLACK AND RED WIRES FROM THE SAME CABLE.


PLEASE HELP IT HAS REALLY GOT MY HEAD DONE IN !! SO CLOSE BUT YET SO
FAR!!


THANKS IN ADVANCE

Hi


It should be the red wire from the three core cable which is in the
COMMON position on your first light switch.


im ok to follow the above

You should have Red and Black (from the light switch) connected across
L1 and L2


so this above means on double switch the cable which leaves the main
single switch should be red to l1 and black to l2.


If it is a single switch (ie. just a red and black wire, and there is
no second switch), then the red and black wires should be in L1 and
COMMON.

If it is a switch with two locations, the red and black wires should
be in L1 and L2. A three core cable is then run between the two
switches (doesn't matter particularly which wires are used so long as
it is the same at both ends)

You should have the three core cable connected across L1 L2 and
COMMON
the above here means the 2 nd set of terminals but what colour wires
go where. sorry for my ignorance.


It doesn't matter as long as it is the same at both ends.
