An operating switch for an oven, comprises first and second switching means individually rotatable about a common axis by means of first and second knobs for selecting a cooking time and a menu option respectively, the first switching means including a shaft movable longitudinally of said axis by pressing the knob for activating a push switch that starts the cooking operation. The first and second switching means include rotary digital encoders that produce digital signals according to the rotation angle of the knobs. The signals, together with signals from the push switch, are input to a microprocessor that controls the cooking operation according to the selected menu and cooking time.

Les premier et second commutateurs comportent des codeurs numériques rotatifs qui produisent des signaux numériques variant en fonction de l'angle de rotation des boutons. Ces signaux ainsi que ceux provenant de l'interrupteur poussoir sont transmis à un microprocesseur qui règle la cuisson en fonction de l'option de menu et du temps de cuisson choisis.
