Thanks for the reply Jeremy.
I've tried various ways to draw neat circuits, and invariably revert to floundering around using MS Paint. I've tried 'Express Schematic', which is a freebie, but as with all software packages, there's a steep learining curve to get into it.
Presumably the switch used for the resistor bank is just a standrd rotary switch of the sort that Maplin sell - the cotacts are rated at 6A continuous, despite their flimsy appearance.
Happy constructing, and thanks once more for the posting.
