Abstract
901,655. Switches held set and freed mechanically. CRABTREE & CO. Ltd., J. A. July 29, 1960 [Aug. 1, 1959], No. 26496/59. Class 38 (5). A dolly-operated doublepole electric switch has one moving contact blade actuated directly by the dolly and the other by an arm or link connected to the dolly. A pair of flexible contact blades 1, 2 are mounted one behind the other and their contacts 8, 15 are spring-urged against fixed contacts 10, 17. Operation of the dolly 3 causes its cammed surface to open contacts 8, 10 and causes a pin 21 to move a pair of links 23, disposed on either side of the dolly. A pin 25 at the other end of the links 23 is guided at its ends in slots 26 in the switch casing and engages the rear contact blade 2 to open contacts 15, 17. A pair of fuse clips are included in one pole and a cartridge fuse engageable with the clips may be mounted on the switch cover. The insulating switch base 6 is embraced by an earth strap 27.
