Abstract
A light-emitting touch-switch device includes a first circuit board, a cap unit and a light-emitting element. The first circuit board is electrically coupled to a sensing chip. The cap unit is disposed on the first circuit board and that is at least partially made of an electrically conductive plastic material having a resistance of equal to or smaller than 1×105Ω. The cap unit and the first circuit board cooperate to define a receiving space. The light-emitting element is disposed in the receiving space and is electrically coupled to the first circuit board. A light-emitting touch-switch module including the light-emitting touch-switch device is also disclosed.
