ABSTRACT:
A layered structure for a keyswitch includes a lower flex circuit layer, an upper flex circuit layer and a spacer layer therebetween. A plurality of projecting flanges are arranged radially and extending from through holes formed in the spacer layer. The flanges may be placed on the lower surface of the upper layer, the upper surface of the lower layer or on the spacer. The flanges separate the spacer and the flex circuit layer such that air passages are formed between each two adjacent flanges, so that a vacuum sucking effect is substantially prevented.
