Mouse and photoelectric control switch thereof

Abstract

The invention relates to a mouse and a photoelectric control switch thereof. The photoelectric control switch comprises a control rod, an optocoupler sensor and an elastic piece, wherein the control rod is arranged in a shell and can move backward and forward between a conducting position and a disconnection position; the optocoupler sensor is arranged on the extension line of one end of the control rod and is electrically connected with the control circuit board of the mouse; and the elastic piece is used for resetting the control rod. The control rod comprises a first end which is close to the optocoupler sensor and is provided with a reflective layer and a second end which is far away from the optocoupler sensor and is used for driving the control rod to be close to the optocoupler sensor; and the shell is provided with a through hole out of which the second end can penetrate. The optocoupler sensor comprises a light-projector and a light-receptor; when the control rod is in the conducting position, the light emitted by the light-projector is received by the light-receptor after being reflected by the reflective layer; and when the control rod is in the disconnection position, the light-receptor can not receive the light which is emitted by the light-projector and reflected by the reflective layer. In the invention, the non-contact type conducting and disconnection control is realized through the match of the optocoupler sensor and the control rod provided with the reflective layer; and the reaction is sensitive and the service life is longer.

Description

technical field [0001] The invention relates to the field of computer auxiliary input equipment, in particular to a mouse and a photoelectric control switch thereof. Background technique [0002] All kinds of control switches such as the left button, the right button, and the middle button on the existing mouse are all mechanical control switches, such as micro switches or membrane switches. There must be a time difference between conduction and conduction, and it is impossible to respond in time; and the contact part used for conduction will be fatigued, deformed or worn during use, and its sensitivity will gradually deteriorate, which will cause There is a limit on the service life. Generally, the effective life of this kind of mechanical switch can only be clicked tens or at most millions of times, which is often the shortest service life among all the parts of the mouse, thus greatly shortening the use of the mouse. Life expectancy, correspondingly increases the use cos...
