In actuating devices such as, e.g., multifunctional actuators, it is necessary in many cases to block at least one specific direction of movement. A simple and reliably operating device is proposed for this purpose, which uses an electromagnet to bring a ball from a rest position into a blocking position. In the blocking position, the ball mechanically blocks the relative movement between two parts.

Actuating device having means for blocking movements

An operating element is provided that has a control knob, which is mounted in a housing, a console, or the like, and can move in a swiveling manner between a home position and multiple switching or contact positions. In order to design the operating element in a simple way, a central momentary switch that establishes the switch actuation point of the operating element and has a haptic function is associated with the control knob, and the momentary switch is actuated each time the control knob is swiveled out of its home position by a predefined angle toward a switching or contact position.
