The outer end of the actuator lever is provided with a downwardly depending pivot leg and pivot or fulcrum support means for the actuator lever is positioned in a plane below the level of the open end of a cylindrical bore in the electromagnetic actuator so that a minimum amount of clearance may be provided between the cylindrical core and the cylindrical bore.
