I'd like to put a socket under the worktop for the dish-washer, and know it's good practice for it to have a switch above in the form of a fused connection unit. I want a socket in the close vacinity of the switch for this spur, and was wondering whether a combined unit is available, or whether I'd need to mount a single switch next to a single socket in a 'twin' pattress? Or could I use a cooker switch and socket, relabelling the word cooker with dymo tape or similar (which I'm loathe to do, as it would imply the circuit was capable of carrying more current)
