At least one embodiment of the invention relates to the fastening and fitting of a built-in unit on a switchboard, which has a through-opening for this purpose, a collar, which is arranged on the built-in, limiting the action of plugging through the built-in unit, and at least one fixing and clamping device ensuring that the built-in unit is pressed correspondingly against the switchboard. In order to specify simple fastening including fitting which can be carried out by a single person, at least one embodiment of the invention proposes that holders arranged on both sides of the built-in unit and having mounts with holding lugs, which are arranged thereon and engage in corresponding depressions and/or apertures of the built-in unit, are provided, that each mount has a web, on which a slide, which latches in stepwise, can be moved toward the switchboard rear side, as a result of which it presses the holding lugs against the depressions and/or apertures and thus fixes the built-in unit in the through-opening first in the intended position, and that sealing of the through-opening takes place by means of clamping elements, which press against the switchboard rear side.

Fastening of a built-in unit on a switchboard and fitting method for fastening a built-in unit

A method is provided for operating an electronic device with control software controlled by means of an operating surface. An interface is disposed between the operating surface and the control software to decouple the operating surface from the control software and transfer any action initiable via the operating surface to the control software.
