Abstract:
1. A photoelectric touch-sensitive linear adjustment switch for an electric appliance, comprising: a housing forming a receiving groove therein, the housing having an outer wall serving as a light-permeable sensing surface to be touched by a human hand; a touch control circuit board provided in the receiving groove, the touch control circuit board having a touch control circuit layer adjacent to the sensing surface, the touch control circuit layer having a surface divided into a plurality of first sensing areas which are arranged along a linear direction; and a plurality of first light-emitting elements provided at intervals on the surface of the touch control circuit layer, each said first light-emitting element being located beside or in a said first sensing area, the touch control circuit layer in each said first sensing area being electrically connected to the first light-emitting element or the first light-emitting elements beside or in the each said first sensing area; wherein when the sensing surface is touched at a position corresponding to a said first sensing area, the touch control circuit layer in the first sensing area is triggered to control light emission of the first light-emitting element or the first light-emitting elements beside or in the triggered first sensing area and to output, according to a position of the triggered first sensing area, a coded signal for controlling a power supply from an external power source.
