A1

A relay, comprising a static contact (12), a movable contact spring lead-out piece (21), a movable contact spring (22) and a movable contact (23). The movable contact (23) is provided on the side of one end of the movable contact spring (22) facing the static contact (12); the other end of the movable contact spring (22) is connected to the movable contact spring lead-out piece (21); and an electro-dynamic repulsion force is generated between the movable contact spring (22) and the movable contact spring lead-out piece (21) when a short-circuit current occurs, so as to enable the movable contact (23) to abut against the static contact (12). Between a position, at which the movable contact spring (22) is connected to the movable contact spring lead-out piece (21), and the movable contact (23), a distance between at least parts of the movable contact spring lead-out piece (21) and the movable contact spring (22) is greater than a distance between a part of the movable contact spring lead-out piece (21), located on two sides of said at least parts, and the movable contact spring (22), so that the use safety of the relay is improved.
