Abstract

A mouse pen and a photoelectric control switch thereof are provided, the photoelectric control switch includes a control rod in a shell moving between on-position and off-position, an optical coupling sensor comprising a light emitter and light receiver disposed on an extension line of the control rod, and an elastic element for resetting the control rod. The control rod includes a first end near the optical coupling sensor and equipped with a reflection element, and a second end for driving the control rod towards the optical coupling sensor which protrudes an orifice of the shell; at the on-position, light emitting from the light emitter is received by the light receiver after being reflected by the reflection element, while at the off-position, light cannot be received. The photoelectric control switch implements non-contact on/off controlling with the optical coupling sensor and the control rod, responses sensitively, and has longer lifetime.

Claims

1. A photoelectric control switch, being set to an mouse device, wherein the photoelectric control switch comprises a control rod which is disposed in a shell and can traverse between an on-position and an off-position, an optical coupling sensor which is disposed on an extension line of one end of the control rod and electrically connected with a control circuit board of the mouse pen, and an elastic element which is used for resetting the control rod;

the control rod comprises a first end which is close to the optical coupling sensor and is equipped with a reflection element and a second end which is far away from the optical coupling sensor and is used for driving the control rod to be close to the optical coupling sensor;

the shell defines an orifice for protruding the second end;

the optical coupling sensor comprises a light emitter and a light receiver, when the control rod is set on the on-position, light emitting from the light emitter can be received by the light receiver after being reflected by the reflection element, while the control rod is set on the off-position, the light receiver can not receive the light emitting from the light emitter and reflected by the reflection element.

2. The photoelectric control switch according to claim 1 wherein the reflection element is a reflection layer which is directly disposed on an outer surface of the first end of the control rod, the shell configures a first limit block corresponding to the first end of the control rod, and configures a second limit block corresponding to the second end of the control rod, the control rod at middle section thereof forms a stop part which is engaged with the second limit block so as to limit a movement of the control rod, and the elastic element is fitted on the control rod with both ends thereof respectively abutting against the stop part and the first limit block.
