    I'm planning to wire in 3 separate lights from a 3 gang switch 1 way. The aim is to take a single t&e from the mcb to the switch point and from there 3 individual t & e cables to each of the lights. Just wanted to double check how to do this using a 2 way switch (I couldn't get hold of a 1 way 3 gang. My plan was to connect the neutral from the mcb to the 3 neutrals from the light fittings using an additional connector and then to connect the live feed from the mcb to each of the L1 connectors using jumpers. I was then planning to connect the live wire from each of the 3 individual light fittings to the COM connector independently of each other (without jumpers). All the earth will be connected at the switch point using a connector too. Does that make sense or is there a better way of configuring this?

    It's more usual to connect the supply to the COM terminals and the individual lights to the L1s, but either way will work.

    When using a two way switch on a one way circuit my preference is supply to L1, This avoids the L2 terminal becoming Live when the switch is OFF

    Surely the proper advice (especially for DIYers) would be to disconnect power before removing switches, sockets, etc.?

    Then it doesn’t matter a jot if L2 might become live.

    It is a carry over from wiring switches like this one where COM and L1 are insulated but the the un-used terminal is left exposed.
