E-bikes combine a bicycle with a big lithium battery, a speed controller, and a motor. What you get from that combination is simple, efficient transportation. [Tom Stanton] wanted to build an e-bike ...

Reed relays contain a reed switch, a coil for creating a magnetic field, an optional diode for handling back EMF from the coil, and an encapsulating package with connection terminals. In many ways, a ...

Electromechanical relays are like dinosaurs who haven’t gotten the news that they are supposed to be extinct. Instead, they beget new generations, get designed into new applications, and even take ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

Reed Switch life characteristics under different levels of capacitive loading. Life tests were run on four types of Coto Technology reed switches at four different, increasingly capacitive load levels ...
