I've pulled apart a wind up head torch, as the switch wont turn it on. Shorting the battery to the diodes lights it up. So the switch has got to provide signal to a resin embedded ic to handle fancy functions like 'flashing' etc. The IC has a49215 on its own mini pcb. Any ideas what this is cause if its knackered I'll want to whip it out and just put in a latched switch to convert the circuit to on or off! The battery is a NiMH so im not sure if the IC mediates charging of the battery instead! Hmmmmm!
