This is an attempt to combine the power switch and lighting in a meaningful element of interior lighting. This light turns on and emerges (spring support) from the wall by easily touching his cap. Turns off as well - click and close it in the wall. Diameter of the fixture may vary from 100-300mm, as well as height - 50-150mm. It can function in 150mm thick wall. The wall and the light is gorgeous and functional interior design element. Let’s say - at a cafe table at home orover the cabinet.
