Abstract
An operating device for an electrical appliance, for example a cooking appliance, is provided with a deformable metallic control panel, underneath which an electret microphone cartridge is disposed. The membrane of the microphone cartridge can be coupled to the lower side of the control panel by means of an elastomer. When pressure is exerted on the control panel by a user pressing on the operating field and causing it to deflect, the membrane of the electret microphone is moved, which in turn causes movement in the microphone and causes a signal that can be evaluated as the operating input by a user.
