Light Switch Change

[Jeremy2014]

Hello Expert, We are looking to change light switches, however, the one we want to change are two way, two gang which bring some complexities.

How can we figure out which cable would go in which hole from the old switch to the new one as the setting seems slightly different from the old and the new.

If needed, the new product we are looking to get is that one

Many thanks,

Your new switch appears. to be marked Com, 1 way and 2way.
Your old one will probably be marked Com, L1 and L2.
Move the wires from one of the Com terminals on the old to the new and the wires in L1 to 1Way and L2 to 2Way.
Repeat for the other switch and remember to connect another similar wire from the green and yellow terminal in the back box to the earth terminal on the face plate of your new switch.

Mark each of the cables AND take photos before you do anything

Your old one will probably be marked Com, L1 and L2.

Be aware the markings on the old switch are in triangles; not top row and bottom row.
