outer layer and the first capacitive component and a second layer of insulating material beneath the first layer of insulating material and in contact with the first capacitive component the second layer having a thru hole encompassing the second capacitive component wherein the second capacitive component faces the first capacitive component at the thru hole and wherein the outer layer is flexibly responsive to pressure and is configured to transfer a flexure to the first capacitive component application_number US 201414526927 A description mechanical pushbuttons comprise movable parts co operating with electrical contacts whose closing or opening generates a particular control signal for the domestic appliance or equipment these buttons however are subject to wear and over time become not fully reliable capacitive controls operate on the basis of the variation of capacitance between two facing conductors one of which is coupled with a surface of the interface that the user is touching these controls suffer in the event of an accumulation of electrostatic charges on said surface however especially when used in domestic appliances such as refrigerators subject to cleaning operations of the outer surface performed using woollen or synthetic cloths other controls can be piezoelectric or make use of.
