Provided is a push-button apparatus, comprising a press assembly (10), a push-button base (20), and an elastic return member (30); the press assembly (10) comprises a push-button cap (11) and a sliding member (12), fixed opposite to each other; the push-button base (20) comprises a main body (21) having a projection, and a protrusion (22) provided with a track groove (23) on the main body (21); the elastic return member (30) is arranged around the outer surface of the protrusion (22) and its two ends elastically abut against the push-button cap (11) and the main body (21), respectively; the track groove (23) at least comprises a first locking position (01) and a second locking position (02); during the process of pressing of the push-button cap (11), the sliding member (12) slides in the track groove (23) and achieves a lock of the first locking position (01) and the second locking position (02). The push-button apparatus comprises only a press assembly (10), a push-button base (20), and an elastic return member (30); the sliding member (12) is relatively fixed on the press assembly (10), and the track groove (23) is provided on the push-button base (20) to allow the sliding member (12) to slide, pushing downward on the press assembly (10) to change the press state of the push-button apparatus; there are few structural members, reliability is high, and service life is longer. |
