<p>A mouse pen and a photoelectric control switch thereof are provided, and the photoelectric control switch includes a control rod (2), an optical coupling sensor (4) and an elastic element (5). The control rod (2) is disposed in a shell (1) and can traverse between an on-position and an off-position, the optical coupling sensor (4) is disposed on the extension line of one end of the control rod (2) and electrically connected with the control circuit board of the mouse pen, and the elastic element (5) is used for resetting the control rod (2). The control rod (2) includes a first end and a second end, the first end is close to the optical coupling sensor (4) and is equipped with a reflection element (7), the second end is far away from the optical coupling sensor (4) and is used for driving the control rod (2) to be close to the optical coupling sensor (4), an orifice for protruding the second end is disposed on the shell (1); the optical coupling sensor (4) includes a light emitter (40) and a light receiver (42), when the control rod (2) is set on the on-position, the light emitting from the light emitter (40) can be received by the light receiver (42) after being reflected by the reflection element (7), while the control rod (2) is set on the off-position, the light emitting from the light emitter (40) can not be received by the light receiver (42) after being reflected by the reflection element (7). The photoelectric control switch implements non-contact on/off controlling with an optical coupling sensor (4) and a control rod (2) equipped with the reflection element (7), responses sensitively, and has a longer useful life period.</p> |
