Abstract

The present disclosure discloses electromagnetic relay capable of resisting short-circuit current, and includes a base (1), a magnetic circuit part, a static spring part (2) and a moving spring part. The static spring part (2) includes a static spring lead-out piece (21) and an elastic static spring piece. The static spring lead-out piece (21) is arranged on the base (1), and the static spring piece (22) is provided with a static contact (221). The static spring piece (22) is electrically connected to the static spring lead-out piece (21), and the static spring piece (22) generates an electric power in the direction of the moving spring part in the energized state, and the electric power can resist the electric repulsive force received by the static contact (221).
