Need to change a switch that operates the bathroom lights.
The switch operates 2 sets of lights (downlights and main lights) and a fan which goes on when the switch for the main lights is on.
The wiring to the existing switch has red, yellow and blue wires going to the switch and an earth wire tucked into the sleeved wires - see picture
The new switch I bought looks like -
Anyone know how to connect the wires to the new switch. And is it correct/safe that the earth wire is not connected??
