    • A contact system of a relay and an electromagnetic relay, the contact system includes a movable spring part (1) and a stationary spring part (2), the stationary spring part (2) includes a stationary spring (21) and at least one stationary contact (22) disposed on the stationary spring (21); where, the movable spring part (1) includes at least one movable spring (11) for providing restoring reaction force and at least one flexible conductive member (13), a conductive ability of the movable spring (11) is weaker than that of the flexible conductive member (13), and the movable spring (11) and the flexible conductive member (13) are connected in parallel to form two connection parts, at least one connection part of the two connection parts is provided with a movable contact (12). The movable spring part (1) of the present disclosure adopts the design of separation of "elasticity" and "current carrying", which can solve the problem of insufficient current carrying cross-sectional area caused by the fact that the movable spring (11) cannot be made thick and wide due to the limited electromagnetic attraction, so that the present disclosure can be applied to a high current environment. The present disclosure can also greatly reduce the heating of the movable spring (11), thereby avoiding the risk of product performance degradation caused by stress relaxation and reaction force reduction of the highly conductive spring at high temperature.
