Model shop - tiny bulbs are used in model trains. (also look at Maplin)
They are also common in car stereos - a repair shop will probably have a selection in stock.
www.cpc.co.uk probably do them as they supply repair shops, but their website is a pain to find
stuff on..!


Thanks. I had a stare in the Maplin catalogue and online but without
success. Maybe I should try harder.

I like the LED route but access is a bit tricky to incorporate a current
limiting resistor - each switch has a pair of these bulb thingys poked
through from opposing sides of the PCB - maybe 12V micro LEDs is the way
to go.

Thanks all.
