Abstract
Abstract An insulation panel having a printed circuit on one surface and is provided with button actuated switch blades on its opposite surface. Each blade is connected through the panel with a portion of the printed circuit, and is opposed to a stationary contact also connected through the panel to a portion of the printed circuit. The switches are preferably actuated by buttons slidably supported above said blades and operable to engage said blades with said stationary contacts with a wiping action.

Claim 1
Independent Claim
290 words
A switch for use in combination with a panel of insulating material including: a spring blade having an anchoring end portion in face contact with the insulating panel, a curved blade portion connected to said anchoring end portion at an acute angle to said panel, said curved blade portion curving gradually toward parallel relation to the surface of said panel and then toward the surface of the panel, an actuating end connected to the end of said curved blade portion along a reversely curved area of short radius providing a convex wiping surface directed toward said panel and in spaced relation thereto, means securing said anchoring end portion in face contact with said panel, a stationary contact on one surface of said panel having a rounded surface in spaced opposed relation to said spring blade, said actuating end of said blade extending from said convex wiping surface in a direction away from said panel and having a reversely curved extremity to provide a convex actuating surface directed away from said panel, said convex wiping surface being between said convex actuating surface and said anchoring end portion, a top panel in spaced parallel relation to said panel of insulating material having an aperture in opposed relation to said actuating end of said blade, and a button slideably supported in said aperture rEmovably bearing against said convex actuating surface and operable, when actuated to flex said curved blade portion to cause engagement between said convex wiping surface of said blade against said stationary contact, further movement of said button acting to flex said convex wiping surface of said blade toward said anchoring end portion to create a wiping action of said convex wiping surface of said blade relative to said stationary contact.
