In 1809 Samuel Thomas von Sömmerring designed an electrolytic relay as part of his electro-chemical telegraph. Solely electrical relays got their start as a further improvement to telegraphs, with American scientist Joseph Henry who is often cited to have invented a relay in 1835 in order to improve his version of … See more A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple See more Since relays are switches, the terminology applied to switches is also applied to relays; a relay switches one or more poles, each of whose contacts can be thrown by energizing the coil. Normally open (NO) contacts connect the circuit when the relay is activated; … See more Relays are used wherever it is necessary to control a high power or high voltage circuit with a low power circuit, especially when galvanic isolation is desirable.
