Electrical accessories include switches, sockets, dimmers, USB charging points, fused connection units, appliance switches, and cable management products. Each serves a specific function in electrical installations. Switches control lighting, sockets provide power outlets, dimmers allow brightness control, and USB points enable device charging without adapters.

A single socket provides one power outlet, while a double socket provides two outlets in the same space. Double sockets are more common in modern installations as they provide flexibility for multiple devices. Both types are available in various styles and finishes. Choose based on space requirements and aesthetic preferences.

USB sockets require standard electrical wiring (live, neutral, and earth) like regular sockets, but they also need to be connected to a USB power supply module. Most USB sockets are designed to fit standard back boxes and can be installed by qualified electricians. USB sockets provide convenient device charging without adapters.
