摘要： A key switch including a base section, a key top, a pair of link members and a switching mechanism. Each link member is provided, at one end region thereof, with a toothed portion meshable with a toothed portion of another link member in a gearing manner and a pivot axle pivotably joined to the base section, and at another end region, with a slide portion slidably engaged with the key top. The base section includes a support plate and a frame member, the frame member being fixedly attached to the upper surface of the support plate. The frame member is provided with a bearing portion pivotably receiving and supporting the pivot axle of each link member. The first end region of each link member is disposed on a lateral side of the frame member and closely to the upper surface of the support plate.

摘要： A key switch used for a keyboard incorporated as an input device in electronic equipment. The key switch includes a support plate; a key top arranged above the support plate; a pair of link members interlocked to each other to support the key top above the support plate and direct the key top in a vertical direction; and a switch mechanism capable of opening and closing a contact section of an electric circuit in accordance with a vertical movement of the key top. The switch mechanism includes a membrane switch sheet carrying the contact section at a position corresponding to the key top and placed on the support plate. Each of the link members includes a sliding part slidably engaged with the support plate. The membrane switch sheet is provided with a through-hole in a region where the sliding part of each link member is engaged with the support plate, the sliding part of the link member being slidably placed on the support plate through the through-hole in the membrane switch sheet.
