KEY SWITCH DEVICE USING ULTRA-THIN ULTRA-SMALL METAL SCISSOR FEET

WIPO Patent Application WO/2016/155672

A1

A key switch device using ultra-thin ultra-small metal scissor feet, said device comprising a keycap (1), a reset element (11), a switch circuit (12) having a switch, a support plate (15) having a matching portion, and a scissor foot support (16) having upper and lower matching portions, scissor lower flat surfaces (17) of a metal inner scissor foot (28) being located outside a scissor upper flat surface (19), scissor lower flat surfaces (17) of a metal outer scissor foot (31) being respectively located inside a scissor upper flat surface (19), the scissor lower flat surfaces (17) and the scissor upper flat surfaces (19) being connected by length bending edges (36), the length bending edges (36) following length directions of scissor foot arms (23). The distance L1 between a length flap upper end surface (42) of the metal outer scissor foot (31) and a central transverse end surface (40) of the scissor upper flat surface (19) is greater than or equal to the distance L between two end surfaces of the length bending edges (36) of the metal inner scissor foot (28). The present solution relates to a key switch device which performs a keystroke operation, and relates in particular to a key switch device mounted in a keyboard which acts as an input device of an electronic apparatus.
