Operating panel for an electronic household appliance such as a cooker having a transistor which adapts the switching behavior of an operating element

摘要

#CMT# #/CMT# The operating panel has at least one operating element (10,12,22) for inputting control values into a controller of the appliance. A display (18) displays input values and/or other information. The controller is arranged to connect at least one operating element of a first type. In addition, or instead of the first type of element, at least one operating element of a second type can be connected to the controller. The second type is a touch switch with a high/low output signal. A transistor circuit is connected between the controller and the contact switch and adapts the switch behavior of the second type of operating element to that of the first type. #CMT#USE : #/CMT# Such as for a cooker or hot plate, microwave oven etc. #CMT#ADVANTAGE : #/CMT# Allows different types of operating elements to be integrated without modification. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block circuit diagram. 10,12 : operating elements 14 : multiplexer 16 : transistor.
