The present invention discloses an electromagnetic relay of bridge contacts. The electromagnetic relay comprises two sets of bridge contact structures composed of four static contacts, four movable contacts and two bridge movable contact springs. In the four movable contacts, one bridge movable contact spring is connected between the two middle movable contacts, and the other one bridge movable contact spring is connected between the two movable contacts at the out sides, so that the middle two static contacts form a set of input/output, and the two static contacts at the outer sides form the other one set of input/output. The connection line of the two middle movable contacts and the connection line of the two movable contacts at the out sides are not in the same straight line, and the connection line of the two middle static contacts and the connection line of the two static contacts at the out sides are also not in the same straight line. According to the present invention, by improving the structures of the bridge contacts, on one hand, the tracking, the pressure and the contact gaps of the two middle contacts can be corrected conveniently, on the other hand, a die for manufacturing products is simple in structure, the parts are easy to manufacture, and the materials are saved.
