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 ...

All credit to Thomas Langewouters for an unusual reed switch ladder circuit for liquid level sensing. You can find it on his website here. He went on to use a more traditional two-terminal design, but ...

The ubiquitous magnetic reed switch has a unique set of properties, including tera-ohm isolation when OFF, milliohm resistance when ON, zero power operation, around one watt hot switching capability, ...

The rise in interest for renewable energy has led to power designers looking for sensors that are fit-for-purpose in high-voltage photovoltaic applications, observes Martin Reizner. Renewable energy ...

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, ...
