Light Switch wires

    Hi guys,

    I'm just wondering my light switch has 3 Natural blue wires and I've got a new light switch that needs a natural wire and wondering do I just pick one from the 3 wires or do I add another wire from the other end of the terminal strip into the light switch?

    It doesn't sound correct having to terminate a neutral into the light switch. Usually just a common (Brown) and switch wire (Brown)

    Can you share another photo of the back of the new switch

    P.S. Ex electrician here

    Yes it is a smart switch it needs a Live in: Brown or red color, live out: Blue to black, and a Natural: blue

    Your switch in the picture looks like a 2 way switch.
    Is it switched somewhere else ?
    That could be a problem for your smart switch.

    Edit- Its not 2 way!

    You need to add a neutral link between the switch and the neutral block. You cannot simply disconnect 1 neutral from the block though as you would lose your neutral circuit. You need an extra piece of neutral cable to go between both.
