摘要： A contact structure of a switch comprises a first contact (1), and one or more doughnut-like second contacts (2) surrounding the first contact (1), and the second contacts (2) are provided with one or more band-like contacts (3a), (3b), (3c), (3d) extending to the opposite side from the first contact (1). With this structure, an area of a metal pattern portion of the second contact (2) becomes smaller as compared with prior art. In a compact electronic device used for a numeric keypad of a mobile telephone or the like, the contact structure can be reduced in size and weight to the utmost and resources can be saved to the utmost.

摘要： An apparatus according to the present invention disassembles bearing caps from a cylinder block and assembles upper metals to the cylinder block and lower metals to the bearing caps. The apparatus is provided with a movable base which is reciprocally moved between a position above a lower metal assembling station and a position above a conveyor lines. A bearing cap disassembling mechanism and upper metal holding mechanism are commonly attached to the movable base. The bearing cap disassembling mechanism disassembles the bearing caps tentatively assembled to the cylinder block and the upper metal holding mechanism holds and assembles a plurality of upper metals to the cylinder block. A moving mechanism is connected to the movable base to move the movable base so that a disassembling operation of the bearing caps from the cylinder block, an assembling operation of the upper metals to the cylinder block, and an assembling operation of the lower metals to the bearing caps are performed within one reciprocal movement of the movable base.
