  • Patent number: 4259558
    Abstract: A multiple cantilever spring contact switch has a plurality of cantilever spring contacts, arranged in one or more series with the spring contacts of a series each clamped at one end in grooves which have base surfaces inclined relative to each other. By this means, predetermined angular inclinations are imposed on the spring contacts, urging the contacts into a correct positional relationship. Particularly the individual contact members are positioned side-by-side at their clamping positions, the free ends of one or more contact members extended laterally to overlie each other. In another arrangement two or more contacts can be stacked, with a spacer member between adjacent contacts, the spacer member having one or more of said grooves.
