<p>A mechanical switch having two contacting sliding plates (1 and 2) which have conductive parts (7 and 9) periodically dispersed in an insulating background (4, 6) with a spatial period and a current assembling member (5, 8) for gathering currents from the conductive parts. A driving device 30 can reciprocate the two sliding plates (1, 2) relatively in parallel to the surface by about half a period. The driving device makes or breaks a current from one sliding plate to the other by displacing the sliding plates. Parallel movement of the plates (1, 2) suppresses the occurrence of arc discharge in breaking a large current. The short stroke of the displacement results in high speed switching. <IMAGE></p> |
