I'm making a simple switch box and I've done quite a bit of looking but I can't find a 4 pole single throw switch anywhere on the major component seller sites in the UK (farnell.co.uk etc.), although I imagine if there is one it wouldn't be reasonably priced.
So, can anybody think of a simple and fairly cheap way I could use a single pole single throw switch to control 4 circuits, or perhaps some alternative to achieve the same goal? Ideally I would like to use a basic rocker switch, but beggars can't choosers.

If consuming power in one of the states is acceptable, you can use one or more relays and energize their coil(s) using a single circuit through the available switch.
There are also "solid state relays" and various do-it-yourself transistor/FET/SCR/etc circuits which could be suitable for switching various types of loads.
