Several different technologies and designs are available among solid-state switches today. The major families are the standard Triacs (triode for alternating current), the snubberless Triacs, and the ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...

Lamp dimmers and their circuits must be compact, energy efficient and able to operate reliably in confined spaces. Lamp brightness is varied by controlling the conduction time of each half-cycle of ...
