ABSTRACT:
The switch comprises a unitary dielectric support member including a base portion to which the fixed ends of a plurality of pairs of cantilever contact springs are secured. Guide portions of the support member define a channel, and a plurality of cam follower portions integrally hinged to the base portion respectively extend between the free ends of an associated contact spring of each pair and the channel. An actuator positioned within the channel includes cam portions for engaging the cam follower portions of the support member and deflecting them so as to displace the associated contact springs.
