ABSTRACT:
A keyswitch device has a good operational feeling in a keytop and is easily and simply assembled. When the keyswitch device is assembled, the engaging pins 55, 56 of the hinge member 47 and the engaging rod 61 of the hinge member 48 are slid on the holder plate 65 toward the open sides of the sliding slots 68, 69 in the holding portions 66, 67 while being guided through the guiding walls 73 . Further, the engaging pins 55, 56 and the engaging rod 61 are slid until the engaging rod 61 rides over the stopper 69A formed in the sliding slot 69. When the guide support member 46 and the keytop 41 are connected with each other, after the engaging rod 53 of the hinge member 47 is opposed to the vertical slot 44 of the keytop 41 and the engaging pins 63, 64 of the hinge member 48 are opposed to the long slot 45 of the keytop 41, the keytop 41 is slightly pressed downwardly. Accordingly, the engaging rod 53 of the hinge member 47 is snapped into the vertical slot 44 while being guided through the guide portion 44A and at the same time the engaging pins 63, 64 of the hinge member 48 are snapped into the long slot 45 while being guided through the guide portion 45A. Thus, not only the guide support member 46 and the holder plate 65 but also the guide support member 46 and the keytop 41 can be easily connected with each other.
