Hi, I'd hoped to be able to replace a faulty 2 gang light switch but I've realised the layout from older switched has changed and I'm confused as to how to map the old wiring to the new layout.
The old switch is a 2 Gang Switch from BS EN 60669 10AX 250V~ which has 2 separate units side by side and this has 7 terminal points and an earth.
The new one is BS EN 60669-1 20-16X 250~ but this has the 2 units now merged into 1 with only 6 terminals point and an earth.
Could anyone help me map the L1, L2 and Com terminals from the old switch to the L11, L12, L21, L22, Com1, Com2 terminals in the new one?
