Abstract
Abstract A switch for electrically connecting a first terminal with a plurality of other terminals. A contact movable into and out of electrical engagement with a plurality of base contacts is employed. The movable contact may comprise physically parallel wires affixed to a flexible plate, as well as wires which radiate radially outwardly from a point. The physically parallel wires may be inclined to the base contacts or the base contacts may be of different thicknesses to achieve sequential contacting of the base contacts by the movable contact. The base contacts may be any convenient shape, or in the form of concentric spirals or interspersed parallel segments or adjacent triangular-shaped segments.
