A control unit for establishing a functional connection between two gearing components comprises at least one control element, which can be moved in order to switch the control unit between different switching states, wherein the at least one control element is configured to provide a retaining force between the gearing components in a first switching state, and to allow movement of the gearing components in relation to one another in a second switching state. An actuator is used to move the at least one control element. A control mechanism controls the actuator. It is provided thereby that the control mechanism is configured to activate the actuator to switch the control unit from the first switching state to the second switching state, in order to move the at least one control element to reduce the retaining force (FH) based on a predetermined delay function (VF).

An electronic device includes a support element, a second cover, a second guiding element and including a pushing element. The support element includes a first cover and a first guiding element. The first guiding element is connected to the first cover. The second guiding element is slidably jointed to the first guiding element to move relative to the first guiding element in a direction and is connected to the second cover. The pushing element is connected to the second cover and configured to push against the support when the second cover rotates relative to the second guiding element to make the support element move relative to the second guiding element.

One aspect is an actuator system having a rotatable drive shaft and a parallel axis friction brake engaged with the drive shaft and configured to provide a drag force on the rotatable drive shaft. The parallel axis friction brake further includes a brake housing and a friction assembly that has at least one parallel axis shaft and at least one clip pressed over the at least one parallel shaft in an interference fit. The friction assembly is engaged with the drive shaft and coupled to the brake housing, at least a portion of the friction assembly rotating with the rotatable drive shaft to create the drag force.
