The invention relates to a suspension arm actuator for an optical scanning device, comprising a suspension arm designed as a two-arm lever and allocated to an optical recording carrier. The suspension arm is, in known manner, mounted to a support between the lever arms such that it can be pivoted about an axis extending perpendicularly to said suspension arm. On its end side, one of the lever arms supports an optical head having optical components, in particular having an objective lens, while a magnetic drive initiating a swivel motion about the axis is allocated to the other lever arm. In addition, the suspension arm actuator comprises a magnetic drive initiating a motion perpendicular to this swivel motion and electric connections between a control unit arranged outside of said suspension arm actuator and the electrical and optical components. The invention solves the problem of designing such a suspension arm actuator such that said suspension arm actuator allows arrangement of an increased number of optical components while keeping or being reduced in its height. To achieve this, electric connections are established by means of line sections arranged at the suspension arm in a plane extending in transverse direction in relation to the axis spaced apart radially from the axis and spaced apart from each other, said line sections each being electrically connected to a contact element for connection of a control line running to the control unit.
