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.
