Abstract
An optical mouse is provided with a conversion unit, a control unit, an optical sensing unit, a light emitting unit, and a switch unit. The conversion unit is electrically connected to a working voltage source, the control unit, and the optical sensing unit. The conversion unit is configured to convert voltage to supply power to the control unit, the optical sensing unit, and the light emitting unit. The control unit is electrically connected to the optical sensing unit. The switch unit is electrically connected to the light unit. When the switch unit is in a turn-off state, the light emitting unit stops emitting light toward a trace surface. The optical sensing unit senses a darkness and transfers darkness data to the control unit. The control unit performs a configured function based on the darkness data.
