摘要: A game switch particularly useful as a bingo table used by a bingo caller has greatly increased reliability over conventional microswitch actuated tables. A matrix of conductive flexible strips are used, whereby when a ball is depressed at an intersection of a vertical and horizontal strip, a contact is made. The resistance of the contact is particularly suitable for use with CMOS gate inputs to an electronic matrix position determining circuit.
