Abstract (en)
[origin: EP0129894A2] A machine control panel includes a matrix of pressure sensitive switches (10) and a matrix of LED's (12) in a substantially coplanar array. An aperture array (18) formed by a flexible cover sheet (16) having an opaque coating (20) surrounding a matrix of transparent apertures (18) is positioned on top of the LED and switch array with corresponding ones of the LED's and apertures in alignment. Unused apertures in the aperture matrix corresponding to unused LED's are selectively closed by opaque aperture covers (19). Switch identifying covers in the form of labels (22) are positioned on top of the aperture array to visually indicate selected ones of the switches (16). A flexible transparent overlay located on top of the aperture array may be used to protect the labels and aperture covers while enabling a switch operating pressure to be transferred to the switches.
