Abstract

440,441. Switch and fuse cases. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. June 30, 1934, No. 19359. [Class 38 (v)] The lid b of an enclosed switch-fuse contains a hole b<1> through which the dolly of the switch projects and is adapted to push the dolly into its " off " position when the lid is swung about its pivot b<3> to open the box. The dolly is then held in the open position by a spring- pressed catch c which moved into latching position when the lid was opened. When the lid is closed a projection d on it presses the catch c back so that the dolly has once again freedom of movement.
