A food or beverage preparation machine, comprising a control panel (5), the control panel (5) comprising an actuator (5x) for setting at least one food or beverage preparation parameter of the food or beverage preparation machine (1) to a predetermined value and a controlling unit, comprises a pressure sensor (6x) electronically connected to said controlling unit for controlling the functioning of the food or beverage preparation machine, and associated with said actuator, said actuator (5x) being pressure-sensitive and comprising a first end (50) with a first deformable surface (51) which is configured to receive a press action (F) from a user, a second end (52) with a second deformable surface (53) which is in physical contact with said pressure sensor (6x), and an elongate portion (54) connecting said first end (50) and said second end (52), said elongate portion (54) being configured to transfer to said second end (52) a pressure that has been generated at said first end (50), such that when a press action (F) is applied to said first deformable surface (51), said pressure is transferred to said second deformable surface (53) by said elongate portion and is applied to said pressure sensor (6x) so as to set said at least one food or beverage preparation parameter.

An interface system for a food or beverage preparation machine, comprising a control panel (5), the control panel (5) comprising an actuator (5x) for setting at least one food or beverage preparation parameter of the food or beverage preparation machine (1) to a predetermined value and a controlling unit, comprises a pressure sensor (6x) electronically connected to said controlling unit for controlling the functioning of the food or beverage preparation machine, and associated with said actuator, said actuator (5x) being pressure-sensitive and comprising a first end (50) with a first deformable surface (51) which is configured to receive a press action (F) from a user, a second end (52) with a second deformable surface (53) which is in physical contact with said pressure sensor (6x), and an elongate portion (54) connecting said first end (50) and said second end (52), said elongate portion (54) being configured to transfer to said second end (52) a pressure that has been generated at said first end (50), such that when a press action (F) is applied to said first deformable surface (51), said pressure is transferred to said second deformable surface (53) by said elongate portion and is applied to said pressure sensor (6x) so as to set said at least one food or beverage preparation parameter.

Devices and method for actuating a switch device (SM) by means of an elastic actuating element with a non-actuating shape 4 without actuating the switch device (SM) and an actuating shape 6 for actuating the switch device (SM).

A food or beverage preparation machine, including a control panel, an actuator for setting at least one food or beverage preparation parameter to a predetermined value and a controlling unit, a pressure sensor electronically connected to the controlling unit for controlling the functioning of the food or beverage preparation machine, the actuator being pressure-sensitive and having a first end with a first deformable surface which is configured to receive a press action (F) from a user, a second end with a second deformable surface which is in physical contact with the pressure sensor, and an elongate portion connecting the first end and the second end the elongate portion being configured to transfer to the second end a pressure that has been generated at the first end, to set the at least one food or beverage preparation parameter.

A key assembly configured to an electronic device is provided. The key assembly includes a switch component and a flexible button. The switch component is disposed in a case of the electronic device. The flexible button has a pressing portion, a shaft portion, at least one water-resistant portion and an actuating portion. The pressing portion is exposed from the case. The shaft portion connects the pressing portion and the actuating portion, and passes through a through hole of the case. The water-resistant portion is connected to the shaft portion and covers the through hole. The actuating portion is located in the case and aligned to the switch component. When a force is applied to the pressing portion, the pressing portion produces compressive deformation and makes the actuating portion produce expensive deformation to actuate the switch component.
