Hi I'm trying to replace a white dimmer switch with a new chrome one. The wiring on the old switch is different to the new one so would like confirmation on how to wire the new switch. The old switch is 2 way 2 gang (although I'm not needing to control lights from another position) there are 2 black cables (with red sheathing) going to each terminal marked C and then there are 2 red cables going to each terminal marked L1. There are 2 earth cables which are twisted together and covered by a raw plug which has been crimped (I can only assume they couldn't be bothered to get some proper earth sleeving!!!!. The new switch is 2 gang 1 way and has a live terminal, a terminal with a large 'S' and a terminal with a wavy line with an arrow going through it. Please can someone confirm how I connect the wiring up to the new switch. Thanking you in advance. Ps I will buy some earth sleeving to cover it properly.
