Movable contact piece for switching device and switching device

The invention provides a moving contact piece for a switching device and the switching device. The movable contact piece can achieve the buffering and damping effects, a movable contact and a static contact are not prone to damage, the service life of the movable contact piece is prolonged, vibration of the switch device to the static contact and the movable contact is small when a switching circuit is closed, the contacts are not prone to damage, the service life is prolonged, and dust-proof, damp-proof and anti-creeping protection can be conducted on the interior of the switching device in the using process. The moving contact piece comprises a moving contact piece body. The moving contact piece body comprises a connecting seat, a pair of moving contact buffer seats arranged on the connecting seat, a moving contact support arranged between the moving contact buffer seats and the connecting seat, and the moving contacts arranged on the moving contact support. 本发明提供一种能够缓冲减震效果，动静触点不易受损，提高动触片使用寿命的用于开关装置的动触片及其在切
