    Abstract

    The invention relates to a leaf spring for an electromagnetic actuator and to such an electromagnetic actuator. The leaf spring is formed as a whole from a disc of plate-shaped, resilient material. The leaf spring comprises a central fastening part, an outer fastening part extending therearound and at least two leaf spring arms extending between the central and outer fastening part. Viewed from the central fastening part, the leaf spring arms (23) have a first zone (24) originating from the central fastening part (21), in which they extend as far as the outer part (22) but for a first clearance (R). The first zone (24) is followed by a second zone (25) in which, without contacting the outer fastening part (22) and proceeding in tangential direction, they bend back as far as the central fastening part (21) but for a second clearance (T).; A third zone (26) follows the second zone (25), in which the spring leaf arms (23) extend towards the outer fastening part (22) to merge therein.
