Abstract

1,014,509. Vacuum switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 30, 1962 [May 2, 1961], No. 15881/61. Heading H2B. In a vacuum switch having two co-operable contacts 1, 2, one contact or each contact has a continuous channel 8 extending into the peripheral side wall 9 adjacent to the contacting face of the contact. The channel may have a narrow width and a depth substantially greater than its width. It is stated that the channel or channels prevent migration of the cathode arc root on to adjacent metal parts.
