A photoelectric joystick handle assembly consists of a joystick handle (1) and a bottom plate (2). Three photoelectric sensors are disposed at the bottom plate. An end of a first linking member (14) and an end of a second linking member (15) are respectively provided with a rotatable first luminous flux variation device (141) and a rotatable second luminous flux variation device (151), and each of the devices is capable of swinging inside a corresponding photoelectric sensor such that a photosensitive component senses continuous changes in light emitted by a light-generation component. An elastic member (18) having an optical path structure (181) is disposed across the second linking member (15) so as to open or close optical paths of the photoelectric sensors, thereby providing a switching signal.
