RELAY

A relay includes a base, a contact part disposed on the base and including two sets of movable contact parts, each set including a movable contact piece, a movable contact unit and a static contact unit; a push rod assembly connected to two movable contact pieces; and a magnetic circuit part arranged on the base for driving the movements of the push rod assembly, so as to drive two movable contact pieces to come into contact or move away from each other, thus the contact part can transit between a connected state and disconnected state. When the contact part is in the connected state, one movable contact piece is deformed under an action of the push rod assembly and has an elastic force, which makes the movable contact piece has a moving tendency to disconnect the contacts.
