Claims

[Claims for Utility Model Registration] (1) A switch grounding member made of a conductive plate material used in a switch attached to a printed wiring board, wherein the conductive plate material has a plurality of fitting parts for the switch. The switch is characterized in that at least one wing-like grounding piece is provided on at least a portion of the plate material and elastically contacts the inner surface of the casing in which the printed wiring board is housed. Earthing member. (2) The fitting part to the switch is the center of the H-shaped slit perpendicular to the longitudinal direction of the conductive plate, and the outline of the contact part with the switch formed in the center is M
2. The switch earth member according to claim 1, wherein the switch ground member is shaped like a letter. (3) The shape of the conductive plate is U-shaped, a fitting portion for the switch is provided on the top surface of the U-shape, and four legs of H-shaped slits are provided extending to the side of the U-shape of the conductive plate. The switch earth member according to claim (2), characterized in that:
