Abstract
A multiple cantilever spring contact switch has a plurality of cantilever spring contacts, in one or more series, with the contacts of each series clamped between surfaces which provided a predetermined relative inclination of the contacts. A pivotal member is mounted on the switch assembly for actuation by an operating member, the pivotal member in turn actuating the contacts. The contact between operating member and pivotal member is localized so that misalignment between operating member and the switch assembly does not affect actuation of the contacts. Such misalignment can occur when the switch assembly or operating member or both are mounted on printed circuit boards. The switch is particularly suitable for a hook switch of a telephone.
