Abstract
A button module includes an operating member, a circuit board having a pattern for detecting touch operations on the operating member, a button arranged on the circuit board, and a light guiding component further including a front side, a back side opposite to the front side, a housing defined between the front and back sides, a recess defined in the back side for hosting a light source, a through hole extending through the front side and connecting the housing to the external space, and an optical path from an inner surface of the recess to the front side. The operating member, the circuit board and the button are located in the housing with the operating member at least partially hosted in the through hole and the button abutting the light guiding component. Light from the light source located in the recess extends along the optical path to the front side.
