Abstract:
PURPOSE: To provide a vacuum switch chamber where volume in structure is reduced, and where the number of parts necessary for closing the vacuum switch chamber is reduced. CONSTITUTION: A vacuum switch chamber 10 has a switch chamber accommodation body 11 comprising two accommodation body parts 12 and 13. The two accommodation body parts 12 and 13 provide a pot or bell structure, and has base parts 20 and 21. These base parts 20 and 21 enclose opening parts 22 and 23 through which support axes 26 and 28 penetrate, and a mounted contact part 27 and a movable contact part 29 are fixed in these axes. The structural size of the vacuum switch chamber 10 is reduced by the bases 20 and 21 drawn inwardly, and moreover, the need for a component and a soldering foil which are needed for a cylindrical switch chamber is eliminated.
