    2 gang 2 way switch with a single rocker

    Does such a thing exist but with one single rocker controlling the switch? i.e. exactly like a normal 2 gang 2 way switch except it is only possible to have both switches in the down position or both in the up. For low current 240V circuit like lighting.

    Single insulated splitcon and KMF

    Hi I've inherited a very tight space, a KMF switch and some split-con for a sub-main to try and tidy up. It's a joyous non-restrained single insulated mess at the moment. The right solution is a different bigger switched fuse, but there isn't room. I don't think the standard KMF shroud could...
