摘要：A food or beverage preparation machine (1) comprising a control panel (5), saidcontrol panel (5) comprising an actuator (5x) for setting at least one beverage

preparation parameter to a predetermined value and a controlling unit for controllingthe functioning of the food or beverage preparation machine (1), the food or beveragepreparation machine (1) comprising in association with said actuator (5x): a light emittingdevice (6x) for emitting a light beam, an element for reflecting the light beam that hasbeen emitted by the light emitting device (6x), the position of the reflecting elementbeing modified when a press action (F) is applied to the actuator (5x), a coupler (8x) forgenerating an interference signal based on the emitted light beam and the reflectedlight beam, a value of at least one parameter of the interference signal depending on theposition of the reflecting element, and a light sensor (7x) for detecting the interferencesignal, said light sensor being electronically connected with the controlling unit, thecontrolling unit being configured for detecting a press action applied to the actuator (5x)based on the value of the at least one parameter of the interference signal so as to setat least one food or beverage preparation parameter.
