Dear John

i know the picture and reason now. suppose the top
join is common C, and the bottom joins are L1 & L2,
suppose C1 means the common join of 1st switch,
C2 is the common join of 2nd switch,
L11 denotes the left join of 1st switch,
L12 denotes the right join of 2nd switch,
L21 denotes the left join of 2nd switch,
L22 denotes the right join of 2nd switch.
(+ve) is the positive join of fluorescent
(-ve) is the negative join of fluorescent

then wire connection will be:

C1 -- (+ve) fluorescent tube (-ve) -- C2
L11 -- L22 and L12 -- L21

or C1 -- (+ve) fluorescent tube (-ve) -- C2
L11 -- L21 and L12 -- L22

both cases above are workable.

because this message box cannot be drawn with a
picture otherwise it will be more clear to know
with the help of pictures.

thanks and regards

vincent
