Industrial and commercial circuits need safe switching, controlled power flow and dependable response during operation. When machines, panels and control systems handle different voltage levels, ...

The relay's primary appeal is its ability to do a lesser-switch's bidding but it's capable of so much more. Relays can be wired together to create very useful, simple, and utterly reliable networks.

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...

The real core of engineering, in addition to technical expertise, is the ability to articulate the inevitable tradeoffs and pros/cons of design alternatives, and then weigh these relative to each ...
