PWM relays allow engineers to go beyond simple "on-off" control to realize significant power savings and reduced heat signatures.

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

Think of the word “relay” and the image that might come to mind is of an old-fashioned telegraph system consisting of a series of magnetic switches that replicate-thereforerecreate and propagate a ...

What’s one to do with some nice little relays of questionable pinout, and prototyping board? How about a quietly clicky 4-bit counter using relay logic with tons of buttons? [Agatha Mallett] ...
