In this current monitoring circuit we use a Reed switch with a LED and a resistor to indicate if is current through a circuit. A Reed switch usually requires between 10 and 100 AT (Ampere-turns = ...

Just about everywhere you go, there’s a reed switch nearby that’s quietly going about its work. Reed switches are so ubiquitous that you’re probably never more than a few feet away from one at any ...

Regular magnets are an irreplaceable solution in many applications in the field of electromechanics. They are used in simple automation (door closing sensors), as well as in more elaborate systems, ...
