キースイッチ
Document Type and Number:
Japanese Patent JP3752206
Kind Code:
B2
Abstract:
A key switch adapted to raise or lower a key top according to need is disclosed. The key switch includes a key top, a link assembly comprised of two link members and operatively connected to the key top, which is retracted by a pressure on the key top and extended by release of the pressure and which has an elastic member at its lower end, an FPC placed on a frame of a keyboard to recognize pressing of the key top, and a plate movably placed on the FPC, to which a lower end of one of the link members is connected, and which has an elastic supporting member being in contact with the elastic member of the link assembly. When the key top is pressed down, the link assembly is retracted while compressing the elastic member of the link assembly and the elastic supporting member of the plate. When the link assembly is further lowered, an elastic resistance of the elastic supporting member is suddenly increased, and thus the elastic member of the first link member is suddenly bent and quickly lowered, thereby affording a click sense to a user and enabling the bent portion of the elastic member to press the FPC.
