| 摘要 | A membrane switch assembly (10) is comprised of spaced apart layers (12, 16) having corresponding patterns of conductive switch contacts (28, 28') arranged in series thereon, the layers (12, 16) being separated by spacing means (20) having openings therein. The switch contacts (28, 28') on each layer are spaced along a single conductive path (24, 24') so that a regular unit value of impedance means exists between the switch contacts (28,28'). When the electrical circuit is completed by closing a switch site, the resulting total impedance is essentially equal to the sum of the unit values of the impedance means along the circuit path formed by the closed switch. | ||||||
