Editing Light switch (section)

==Design==
The switches may be single or multiple, designed for indoor or outdoor use. Optional extras may include dimmer-controls, environmental protection, weather and security protection. In residential and light commercial lighting systems, the light switch directly controls the circuit feeding the lamps. In larger lighting systems, for example warehouses or outdoor lighting systems, the required current may be too high for a manual switch. In these systems light switches control lighting [[contactor]]s, a [[relay]] that allows the manual light switch to operate on a lower current, with smaller wiring than would be required in the main lighting circuit.

In the UK, putting 13-ampere [[BS 1363]] sockets on a lighting circuit is discouraged (although not outright prohibited), but 2-ampere or 5-ampere [[BS 546]] outlets are often put on lighting circuits to allow control of free-standing lamps from the room's light switches. In North American site-built and [[mobile home]]s, often living rooms and bedrooms have a switched receptacle for a floor or table lamp. Such receptacles are referred to as ''{{visible anchor|switched outlets|Switched outlet}}'' or ''{{visible anchor|half-hot outlets|Half-hot outlet}}''.<ref>{{cite web |date=February 13, 2019 |url=https://www.rockwallelectric.com/post/whats-the-deal-with-the-coordinated-outlet-switch |title=What's the Deal with the Coordinated Outlet Switch? |publisher=Rockwall Electric |archive-url=https://web.archive.org/web/20200930215439/https://www.rockwallelectric.com/post/whats-the-deal-with-the-coordinated-outlet-switch |archive-date=September 30, 2020 |url-status=live }}</ref>
