ABSTRACT:
A button apparatus includes a button, a cover pivotally engaged with the button, and a chassis secured to the cover. The chassis includes a frame, an opening defined in the frame, and an elastic element connected between two opposite sides of the frame. The elastic element includes a first contact portion and a second contact portion. The button includes two pressing portions extending outwardly from two opposite sides thereof. The two pressing portions are arranged at two opposite sides of the elastic element. When the button is depressed, it moves relative to the cover from an original position to a depressed position, causing one of the first and second contact portions to be resiliently distorted and abut one of the two opposite sides of the body. When the button is released, the elastic element restores the button to the original position.
