Electrical component - An electrical component is any component in the generation, transmission, distribution, or consumption of electric power. Some examples of these components would be: relays, contactors, timers, circuit breakers, fuses, and motor starters.

A Symbolic Analysis of Relay and Switching Circuits - In his 1937 MIT master's thesis, A Symbolic Analysis of Relay and Switching Circuits, Claude Elwood Shannon proved that Boolean algebra and binary arithmetic could be used to simplify the arrangement of the electromechanical relays then used in telephone routing switches, then turned the concept upside down and also proved that it should be possible to use arrangements of relays to solve Boolean algebra problems. This concept, of utilizing the properties of electrical switches to do logic, is the basic concept that underlies all electronic digital computers, and the thesis became the foundation of practical digital circuit design when ...

Minivac 601 - Minivac 601 Digital Computer Kit was an eletromechanical digital computer product created by Claude Shannon and sold by Scientific Development Corporation as early as 1961 as an educational kit for digital circuits. It used electrical relays as logic switches and for storage.

Zero cross circuit - A zero cross circuit is an electrical circuit that starts operation with the AC load voltage at close to zero-phase. This is in relation to solid state relays, such as triacs and silicon controlled rectifiers.
