Sometimes, the most unexpected detours lead to the most interesting discoveries. After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be ...

The 385 series of mechanically-latched, electrically-reset relays are used where the relay contacts need to remain in the last set position with the power off. The terminals have a single-piece ...

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

Most of Europe’s 240 million electricity meters are expected to be replaced by smart meters by 2020. It is currently estimated that approximately 78 million of these meters will need to use AC ...

Adafruit has today announced a new addition to their range of FeatherWing add-on boards with the availability of two FeatherWing relays that offer both latching and non-latching and are now available ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Large scale digital logic began not with the vacuum tube but the electromechanical relay. Although vacuum tubes were available at the time – and were used on competing machines – Konrad Zuse chose to ...
