Zusammenfassung:The utility model discloses a relay contact group capable of preventing contact points from bonding. The relay contact group comprises a movable contact group and a fixed contact group, wherein the movable contact group comprises a movable contact piece; the fixed contact group comprises a fixed contact piece; the relay contact group is characterized in that a groove is formed in the upper part of the movable contact piece, so that a first cantilever and a second cantilever which are parallel to each other are formed at the upper part of the movable contact piece; an auxiliary movable contact point is fixedly arranged at the upper part of the first cantilever; a main movable contact point is fixedly arranged at the upper part of the second cantilever; a main fixed contact point corresponding to the main movable contact point and an auxiliary fixed contact point corresponding to the auxiliary movable contact point are fixedly arranged at the upper part of the fixed contact piece. The relay contact group has the advantages that when a relay using the relay contact group is used in a load circuit with larger surge current, the contact points are effectively prevented from bonding.
