Abstract: The invention relates to a switch element including an actuating element that can be impinged upon by an energy accumulator (force storage device) and is mounted so that it can be moved along a trajectory. At least two energy accumulators are used to impinge the actuating element and the number of the energy accumulators impinging the actuating element varies in predetermined positions of the trajectory.

Abstract: An open-loop or closed-loop control device for electric components which are arranged in or on a piece of furniture or a part of a piece of furniture, having: a microprocessor, which carries out the open-loop and/or closed-loop control functions during operation, and an interface for wire-free communication between the open-loop or closed-loop control device and the outside world, wherein the microprocessor and the interface are arranged in a common housing and are arranged either on printed circuit boards which are detachably attached to one another or on printed circuit boards which are arranged separately from one another in or on the open-loop or closed-loop control device.

Abstract: The invention relates to a piece of furniture comprising a furniture body, a furniture part that is mounted so as to be mobile relative to the furniture body and a drive device for moving the furniture part, which drive device can be triggered via a switch element and comprises at least one motor. The switch element is covered by the furniture part in or on the furniture body when the furniture part is closed and an indirect actuation of the switch element via a force exerted by a user and impacting the mobile furniture part triggers the drive unit. The switch element triggering the drive device is accessible for the user and can be directly actuated when the furniture part is moved out of the closed position.
