Hello Trevor, yes I had considered that and I remember the Makaswitch but they're more than I'm prepared to pay!

Tony, I think I'll be going along with your suggestion. I spent an hour looking at it yesterday and I think it could be done with three or four 74HC08 (Quad 2 input AND). I've got one, they're still quite cheap to buy and I have a 1P4W BBM rotary switch.

In the meantime, I'll keep my eyes open for a switch!
