I have an LED diving flashlight that uses a Hall effect sensor for switching it on.
The strange thing is that this switch seems to be affected by gavity. When i hold the flashlight upright, pointing at the sky and just barely turn it on (the switch is like a dimmer switch) and then point it downwards, the light goes out. There are no parts that could be loose! How does one explain this effect. Looking online, I cannot find anything on a gravity effect on Hall switches.
@unavant,
Wow Vant that's a good'n. What happens if instead of barely you switch it on fully
@dalehileman,
Hi
dalehileman, good to see you again.
unavant, you say no parts can be loose, but I suspect the globe is.
It's al solid state -a circuit board with parts, including the LEDs soldered on. There is nothing that could possibly be loose. There is no effect at full-on.

You can certainly have a dry joint develop in solder. If you have a soldering iron, just refresh any joints that look a bit suspect.
Or, since there is no effect at full power, don't worry about it.
