<P>PROBLEM TO BE SOLVED: To solve such problems that the dielectric breakdown voltage of a single vacuum chamber is rather limited, more than one vacuum chamber or vacuum circuit breaker is used in the same switching device, and switching is performed by a single mechanism. <P>SOLUTION: A switching device 100 has a single operation mechanism generally shown by reference number 60. The mechanism 60 is a unique mechanism adapted to operate both first movable contact assembly 40 and second movable contact assembly 50 between a first position and a second position. At the first position, a first movable contact 41 and a second movable contact 51 are electrically connected with a first fixed contact 31 and a second fixed contact 32, respectively, in at least one vacuum chamber 20. At the second position, the first movable contact 41 and the second movable contact 51 are electrically separated from the first fixed contact 31 and the second fixed contact 32, respectively, in at least one vacuum chamber 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
