Switch assembly

摘要

Upon depression of a depression surface (7) of an operating knob (6) of a switch assembly (1), a depression working surface (10) pushes down the head portion of a rubber contact (5), and a switching operation is performed. The operating knob (6) is pushed up by the return elastic force of the rubber contact and returned to its original position. Then the upper face of the depression portion (9) abuts against the correction member (4). As the correction member (4) is positioned directly above the rubber contact (5), the moment generated by the return elastic force of the rubber contact is offset and the operating knob is straightened and maintained to be in a horizontal position. Therefore, the side surfaces of the head portion (8) projecting from the operation hole (3) of the switch case barely rub against the side edges of the operation hole (3) in a depressed state owing to inclination of the operating knob. <IMAGE>
