<p><P>PROBLEM TO BE SOLVED: To provide a method of securing insulation properties among switching terminals which enables a high withstand voltage between switch terminals to be secured at low cost. <P>SOLUTION: Three pair of bushings 31-33, each of which extends upward and is provided with terminals 41-43, respectively at each upper end side, are arranged, and an adjustment adaptor 5 is arranged at the lower end of the second bushing 32 positioned at the center, to make the height position of the terminal 42 of the second bushing 32 higher than that of the terminals 41, 43 of the other respective bushings 31, 33. As a result, a distance L2 between the terminal 42 of the second bushing 32 and the terminals 41, 43 of the other respective bushings 31, 33 adjacent to each other is made larger so that a predetermined withstand voltage between the terminals is obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
