发明名称 Membrane-type touch panel
摘要 In a membrane-type touch panel including a pair of circuit layers having facing conductive circuit patterns normally separated by spacers defining voids through which regions of the circuit patterns can move to effect actuation, a series of projections are provided which, upon actuation, are adapted to act inwardly upon the outer surface of at least one of the two circuit layers at regions aligned with corresponding voids to reduce the required actuation force or to allow a reduction in the size of the spacer voids to reduce the possibility of false actuations.
