ABSTRACT:
The invention relates to a manually actuated switch of miniature size wherein a circuit path is completed between poles of the switch by a contact having independent cantilever beams contacting a respective switch pole. The contact is carried by a manually displaceable sliding element in the form of a carriage. Movement of the carriage causes wiping of the cantilever beams over a substantial length of the switch poles. To interrupt the circuit the sliding element is moved to an extreme position whereby one of the beams is slidably traversed off a corresponding switch pole and into abutment against a dielectric projection which prevents chatter of the disengaged beam. Detenting action for precise positioning of the slider element is accomplished by sliding at least one of the cantilever beams over an irregular surface of one of the switch poles. To maximize cantilever beam length, each beam originates on one side of the slider element, projects diagonally across the free space under the slider element and slidably contacts a corresponding switch pole. Since the cantilever beams diagonally bridge across the entire length of the free space under the slider element the beams are of maximum permissible length assuring resiliency over a substantial range of deflection. The component parts of the switch are fabricated for ease in assembly. The switch poles are embedded in a dielectric material which is injection molded to a desired housing shape. The slider element also is injection molded with the contact embedded therein. By forming the contact and the switch poles to desired shapes subsequent to molding, the component parts stack together without a need for hand assembly of the dielectric and conducting component parts.
