Hello--I am a new member of this forum, in fact I joined to ask this question.
I am trying to determine what type of device I would need to act as a switch or trigger by moving it to within 6 inches of another component. I don't know whether both would have to be powered, or if one could be of a non-powered nature, such as a magnet. Both components need to be rather small in size, say the size of a wristwatch or smaller. I know very little about electronics, and any help would be greatly appreciated. Marsh
