I've got a 3V button battery driving an led and a trembler switch functioning now. However, the sensitivity of the switch is giving me trouble because I need it to remain open when at rest in a horizontal and vertical state and only open when set into motion. This works sometimes but is very difficult to duplicate reliably. The answers to my last post helped a lot but I wanted to try one last tack. If I replaced the trembler switch with a tilt switch it would be 100% reliable to activate every time it was tilted from vertical, but would unfortunately remain on when horizontal which I need to avoid. I have tried to find a very small (I only have about a 1/2 inch of space to work with) tilt switch that is open in the vertical and horizontal planes. The best would be if I could find a component like that. Barring that, what would be the simplest possible way to alter the circuit so that it would turn off again after some short period of time like a second and only reset if the switch turns off again? Thanks for any help. -Rory
On the comment regarding using a capacitor, how would I determine the correct capacity to choose besides trial and error?
