Abstract

1,018,250. High-voltage switches. S. & C. ELECTRIC CO. May 25, 1964 [July 15, 1963], No. 21437/64. Heading H2B. A switch, such as the disconnecting switch associated with a circuit-interrupter as in Specification 966,110, has a pair of inverted U-shaped flexible arcing horns 55 engaging with opposite sides of an arcing tip forming an extension of the free end of a swinging switchblade (not shown) the arms of each arcing horn being of unequal length with the longer arm 58 being fixed and the shorter arm 56 being free to flex when engaged by the arcing tip. The arcing horns are staggered in parallel planes and are interconnected by a tie-bar 64. The switch blade swings about a transverse axis and also turns about its own longitudinal axis to bring contact " ears " into high pressure engagement with fixed main contacts 36 which are U-shaped, interconnected by a pin 43 and a link 46 and reinforced by springs 39. A stop plunger arrests the movement of the switch-blade with a cushioning effect provided by bumper pads.
