Contact piece structure and magnetic latching relay

Abstract

A contact piece structure comprising two movable contact pieces arranged side by side, each movable contact piece comprising: a piece body comprising a plurality of spring pieces stacked with each other, wherein a gap is formed between adjacent spring pieces; a movable contact and a static contact located at opposite ends of the piece body; wherein the movable contact and the static contact of one of the movable contact pieces correspond to the static contact and the movable contact of the other movable contact piece respectively, so that when the movable contact and the static contact are in contact, the two movable contact pieces form a parallel circuit structure; at least one movable contact piece further comprises: a bump disposed in the gap and connected to at least one spring piece.
