Socket - Socket (English spelling)

Japanese: ソケット - そけっと(英語表記)socket
Socket - Socket (English spelling)

It means "hole, socket", but generally refers to the socket for light bulbs in electrical wiring devices. Screw-in type (mainly right-hand thread) is the norm, but plug-in types are also available. Made of porcelain or synthetic resin, they are classified according to the type of bulb used, such as large, regular, medium, thin, and small. Shape specifications are stipulated by JIS (Japanese Industrial Standards).

Sockets for corded hanging lights come in two types: key sockets with a flashing key, and keyless sockets without a flashing key. There are also wired sockets, which have a wire directly connected to the keyless socket in advance instead of connecting via a cord. When wired sockets are to be used in humid locations, there are wired waterproof sockets. Sockets used in general electrical facilities are designated as specific electrical appliances under the Electrical Appliance and Material Safety Act, and their manufacture and sale are subject to regulations.
