Abstract
A button assembly comprises an insulation body, a first contact terminal, a second contact terminal, a third contact terminal, a first movable terminal, a second movable terminal and a pressing piece, wherein the first contact terminal, the second contact terminal and the third contact terminal are fixedly held in the insulation body; the first movable terminal is located above the first contact terminal; the second movable terminal is located above the second contact terminal; and the pressing piece can act on the movable terminals. The pressing piece is installed on the insulation body. The pressing piece comprises a pressing portion and an embossment portion which is protruded towards a movable terminal direction, wherein two ends of the pressing portion are extended so as to exceed the insulation body. When a force is applied to the pressing portion, the pressing portion drives the embossment portion to move towards the movable terminal direction. When the first movable terminal is pressed by the embossment portion and then is connected to the corresponding first contact terminal, at this time, the first contact terminal is connected to the third contact terminal. When the second movable terminal is pressed by the embossment portion and then is connected to the corresponding second contact terminal, at this time, the second contact terminal is connected to the third contact terminal.
