A non-contact switch and a non-contact switch control system are provided. The non-contact switch control system includes multiple non-contact switches, each including an infrared light module, a brightness sensing unit, a second switch module and a processing unit. The infrared light module includes a first switch module, transmitting unit and receiving unit. The first switch module has a first switch state. The transmitting unit connected to the first switch module emits infrared light according to the first switch state. The receiving unit receives a reflected light of the infrared light. The brightness sensing unit generates brightness information according to an ambient light. The second switch module has a second switch state. The processing unit is connected with the infrared light module, the brightness sensing unit and the second switch module, and controls the second switch state according to the reflected light and the brightness information.

An optical diffusing element includes a light emitting surface. The light emitting surface has microstructures, each microstructure has a border, the border of each microstructure is completely connected with the borders of the adjacent microstructures, each microstructure has a surface profile, and a functional formula of the surface profile is: s(x) represents the surface profile of each microstructure on an x-axis. The value x represents a vertical projection position of the surface profile on the x-axis. The value R represents a curvature radius of a vertex of each microstructure. The value κ represents a conic coefficient of each microstructure. The microstructures have the same value R and value κ. A light emitting assembly for three-dimension sensing includes the optical diffusing element and a light source. The optical diffusing element and the light emitting assembly for three-dimension sensing have the advantages of controlling light shape, light profile and simplifying design.
