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.

A switch comprising:
- a pair of cantilever contact springs, the fixed ends of the contact springs being electrically insulated from one another and the free end portions of the contact springs extending into juxtaposition with one another and having contact surfaces for engaging one another;
- a unitary support member including:
- 1. integral base means to which the fixed ends of the contact springs are secured,
- 2. integral guide means defining a channel, and
- 3. integrally hinged cam follower means extending between the free end portion of a first of the contact springs and the channel, the support member being electrically insulated from the contact springs;
- and
- an actuator positioned within and displaceable along the channel, the actuator including cam portions for engaging the cam follower means and deflecting them so as to displace the first contact spring to effect operation of the switch.
