  2. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    The momentary switches usually have SPDT contacts in an (ON)-OFF-(ON) configuration. Pushing the switch actuator in one direction causes the relay contacts to close; pushing it in the opposite direction causes the relay contacts to open. Any number of additional rocker switches can be wired in parallel, as needed in multiple locations.

  3. Shunt (electrical) - Wikipedia

    en.wikipedia.org/wiki/Shunt_(electrical)

    A shunt resistor, which has been connected in parallel across the filament before it burnt out, will then short out to bypass the burnt filament and allow the rest of the string to light. If too many lights burn out however, a shunt will also burn out, requiring the use of a multimeter to find the point of failure.

  4. Recloser - Wikipedia

    en.wikipedia.org/wiki/Recloser

    Modern automatic circuit reclosers are significantly more advanced than the original hydraulic units. The advent of semiconductor based electronic protective relays in the 1980s resulted in increased recloser sophistication, allowing for differing responses to the various cases of abnormal operation or fault on an electric power distribution ...

  5. Contactor - Wikipedia

    en.wikipedia.org/wiki/Contactor

    A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. Unlike general-purpose relays, contactors are designed to be directly connected to high-current load devices. Relays tend to be of lower capacity and are usually ...

  6. Solid-state relay - Wikipedia

    en.wikipedia.org/wiki/Solid-state_relay

    A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay , but solid-state electronics contain no moving parts and have a longer operational lifetime.

  7. Dry contact - Wikipedia

    en.wikipedia.org/wiki/Dry_contact

    Dry contact may mean any of the following in electronics: . No current: A dry contact is the synonym of volt free — it is not "wetted" by a voltage source.Dry contact can refer to a secondary set of contacts of a relay circuit which does not make or break the primary current being controlled by the relay.
