  • Patent number: 4083100
    Abstract: An improved method is disclosed for manufacturing a keyswitch assembly which includes a plurality of switches in a predefined arrangement on the face of an insulative circuit board and which also has a protective, insulative coating over the switches and board face. Each of the switches includes a pair of spaced contacts on the board face and a resilient, deformable, electrically conductive actuating element which can be selectively deformed to provide an electrical circuit between the two contacts. The method is performed with the aid of a planar template having a plurality of apertures positioned in a predefined arrangement corresponding to the arrangement of the switches on the circuit board. As an initial step, an insulative sheet, eventually forming the coating, is placed on a flat surface and the template is placed on top of the sheet so that the sheet is sandwiched between the template and the surface.
