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, ...

When to use mechanical vs. solid-state devices. The parameters that should be considered when selecting a device. Optimize your selection for lowest cost/maximum ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

The differences among the types of signals that a test system’s switching hardware must handle are not always well understood. But if these differences are not taken into account in switch system ...

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.

Switched mode power supply units (SMPSUs) are popular but difficult to build oneself as well problematic when it comes to understanding their design principles. Building your own SMPSU typically ...

A relay module is an electrical component. Various industries use this circuit board that houses one or more electric switches or relays in different circuits and electrical projects. Relay boards are ...
