When designing equipment with switching functions, most engineers find that switching high currents and high voltages is a major problem. A solid-state solution may be possible, but it’s complex and ...

High voltage relays are electromechanical devices used to switch high voltage (> 1kV) signals. They operate using the same basic principles as electromechanical relays, but include features designed ...

Electrical contactors are devices used to switch electrical circuits on and off. They are designed to handle high current loads and are typically used in applications where frequent switching is ...

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.
