A switch panel assembly is mounted on a wall and has a switch panel, a light-guiding rod, a circuit board and a switch. The switch panel has two lamp holders formed on and protruding from the switch panel. The light-guiding rod is mounted between the two lamp holders. The circuit board has at least one lamp held in the lamp holders and an optical sensor held in one of the lamp holders. The switch is connected electrically to an illuminating device. The optical sensor is used to detect ambient lights such that the at least one lamp can be automatically lighted up when an ambient environment is dark. The light-guiding rod guides, refracts and scatters the lights emitting from the lamp to brighten the ambient environment for a people easily and quickly finding and switching the switch.
