A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...

E39d Three-way Mogul (modified socket with additional ring contact for 3-way lamps) E40s European; Skirted (PAR-38) The light bulb commonly used since the early 20th century for general-purpose lighting applications, with a pear-like shape and an Edison screw base, is referred to as an "A-series light bulb." This most common general purpose ...
[3]: fig.8 The Sawyer-Man or Westinghouse base used a spring clip acting on grooves in the bulb base and a contact stud at the bottom of the lamp. [3]: fig.7 Most smaller competitors had to produce lamps for all three types, [2] and some used their own designs as well. [4] Other lamp bases include the bayonet mount and wedge base.
No 3-way lamp support. Incompatibility with other bulb types. Will maintain a price premium while they are mandated in a minority of jurisdictions. While the pins spacing is standardized, there is no standard for base width. Some fixtures shroud or recess the socket, assuming base dimensions of the bulbs they came with.
Hybrid connectors allow the intermixing of many connector types, usually by way of a housing with inserts. [19] These housings may also allow intermixing of electrical and non-electrical interfaces, examples of the latter being pneumatic line connectors, and optical fiber connectors. Because hybrid connectors are modular in nature, they tend to ...
Connectors on this cable would be designated: 1A1W35P1; 1A1W35P2; ASME Y14.44-2008 continues the convention of Plug P and Jack J when assigning references for electrical connectors in assemblies where a J (or jack) is the more fixed and P (or plug) is the less fixed of a connector pair, without regard to the gender of the connector contacts.
AC power plugs and sockets connect devices to mains electricity to supply them with electrical power.A plug is the connector attached to an electrically-operated device, often via a cable.
