BACKLIT TOUCH BUTTON ASSEMBLY
First Claim
1. A backlit touch button assembly, comprising:
- a circuit board;
at least one light source positioned on the circuit board; and
a reflecting plate and a marked strip attached to opposite sides of the circuit board;
wherein the reflecting plate defines at least one optical groove receiving the at least one light source, the at least one optical groove comprises a reflecting portion, the circuit board defines at least one through hole adjacent to the at least one light source, and the at least one through hole corresponds to the reflecting portion, the reflecting portion comprises a first reflecting surface, a second reflecting surface, and a third reflecting surface, and the first reflecting surface and the third reflecting surface meet the second reflecting surface, respectively.

Abstract
A backlit touch button assembly includes a circuit board, one or more light sources, a reflecting plate, and a marked strip. The light sources are positioned on the circuit board. The reflecting plate and the marked strip are attached to opposite sides of the circuit board. The reflecting plate defines one or more optical grooves receiving the light sources. Each optical groove has a reflecting portion. The circuit board defines one or more through holes adjacent to the light sources and corresponding to the reflecting portion of the optical grooves. The reflecting portion has a first reflecting surface, a second reflecting surface, and a third reflecting surface. The first reflecting surface and the third reflecting surface meet the second reflecting surface, respectively, at an angle.
