2. Light switch - Wikipedia

   en.wikipedia.org/wiki/Light_switch

   The toggle light switch was invented in 1916 by William J. Newton. [2] As a component of an electrical wiring or home wiring system, the installation of light switches is regulated by some authority concerned with safety and standards. In different countries the standard dimensions of the wall mounting hardware (boxes, plates, etc.) may differ.

3. Wireless light switch - Wikipedia

   en.wikipedia.org/wiki/Wireless_light_switch

   Wireless light switches eliminate the wire from the light to the switch location. This is useful in remodelling situations where new wiring can be a hassle. Rather than tearing down a wall to gain access to the wires, a wireless switch can be used. This avoids any need to access wires and makes remodelling fast and simple.

4. Multiway switching - Wikipedia

   en.wikipedia.org/wiki/Multiway_switching

   In contrast to a simple light switch, which is a single pole, single throw (SPST) switch, multiway switching uses switches with one or more additional contacts and two or more wires are run between the switches. When the load is controlled from only two points, single pole, double throw (SPDT) switches are used.

5. Pull switch - Wikipedia

   en.wikipedia.org/wiki/Pull_switch

   Pull switches may be either two-position (open or closed) or multi-position (allowing for different fan speeds or levels of illumination). Mounted inside a pull switch, there could be two types of two-position toggle switches. (In both cases the stable physical open- or closed -situation would be switch in outer and string in upper position.)

6. Heating, ventilation, and air conditioning - Wikipedia
