ABSTRACT:
A mechanical switch having two contacting sliding plates which have conductive parts periodically dispersed in an insulating background in a spatial period and a current assembling member for gathering currents from the conductive parts, and a driving device for reciprocating two sliding plates in parallel to the surface relatively by about half a period. The driving device cuts or leads a current from one sliding plate to the other by displacing the sliding plates. Parallel movement of the plates suppresses the occurrence of arc discharge in shutting a big current. The short stroke of the displacement gives high speed switching to the device.
