Abstract
An elongated key switch 1 includes a key top 2 and a guide support member 5 supporting the key top 2. The guide support member 5 includes connection members 3c, 4c formed in a thick plate or rod shape to provide them which high rigidity. The connection member 3c is provided with a press-down portion that directly presses down on a rubber spring to perform a switching operation. To insure that the connection member 3c is sufficiently rigid so that the switching operation can be performed, metal wire 3g having rigidity is press fitted in a lengthwise direction of the connection member 3c. Accordingly, even when a lengthwise end portion of the key top 2 is pressed down, the connection members 3c, 4c, particularly the connection member 3c that presses directly on the rubber spring, will not bend. As a result, switching operations can be accurately performed.
