Abstract
A switch panel with an indicator is disclosed. The switch panel has a transparent region. There is a light source disposed in the switch panel for emitting light when turning off a switch body. A shape of the transparent region is projected onto the wall for forming a large area of indicating pattern, and this can replace a night light. The drawback of a luminous region in prior art which is limited to be on the switch body or on the switch panel is solved.
