Abstract
The present invention discloses a photoelectric joystick assembly composed of a joystick and a substrate, the substrate being provided with three pairs of photoelectric tubes; first and second linkage members are respectively provided with rotatable first and second luminous flux changing members at one end, thereby oscillating in the respective photoelectric tubes, respectively, so that the light received by a photosensitive element from a light-emitting element continuously changes; the second linkage member is further provided with an elastic member with a light path mechanism thereacross, which acts on communication or block of the light path of the photoelectric tubes to provide a switch signal. The solution of the present invention is to replace the mechanical contact switch and potentiometer for transmission with a photoelectric element and an original structure, and design a connection structure and manner originally, by which these photoelectric elements are arranged in the rocker masterly. Accordingly, the mechanical mechanism is separated from electricity, so as to make a coating on the substrate dustproof, waterproof and antistatic, and further, non-contact photoelectric elements prolong service life of a product greatly. The rocker assembly has wide applicability and strong practicability, and thus has broad market prospects.
