The invention relates to a slider actuator (203) suitable for controlling relative movement between sliding elements (201, 202). The slider actuator includes two or more contact parts (209, 210) capable of forming mechanical contacts with one of the sliding elements in at least two locations of that sliding element (201). Each of the at least two contact parts is capable of supporting the sliding element in mutually opposite directions. The fact that the slider actuator includes two or more contact parts that are capable of supporting a sliding element in mutually opposite directions in different locations of the sliding element makes possible, for example, to extend the maximum range of movement of the sliding elements and/or to in crease a number of stable mutual positions of the sliding elements.
