A soft-collision electromagnetic driving mechanism comprises a movable shaft driven by an electromagnetic mechanism, wherein the movable shaft is fixed to a movable iron core, an upper part of the movable shaft is connected to a movable damping mechanism, the movable damping mechanism comprises a first cylinder, the first cylinder has a movable damping piston therein, the movable damping piston is formed by a damping piston head and damping piston rods disposed at two sides of the damping piston head, first and second sealing chambers are at the two sides of the damping piston head respectively, a damping liquid is filled in the first and second sealing chambers, and a two-way discharge channel is arranged between the first and second sealing chambers. The driving mechanism is a permanent magnetic linear driving mechanism having a simple structure, a strong driving force and smooth contact, which can be used to drive electrical switches or devices requiring smooth contact, strong driving force and high speed.
