I have an Iron man helmet with 2 colour led eye that switch from a single button,
the led`s are linked together with no other parts just connected to a 5v red / black wire
supply on a small pcb, there are parts in the switch that do it, I have seen the posts on using a 555 timer
or a npn transistor but looking at the circuits there would still be 3 wires, anyone know
what parts in the switch would do this , hold off one led `press` switch to the other and
so on....
