Abstract
470,659. Switch handles. PRENTICE. H. B. April 17, 1936, No. 11023. [Class 38 (v)] A detachable switch handle 6 is formed with a short spindle 4 having keys 9 adapted for driving connection with slots on a boss of a switch operating lever. In the off position of the switch these slots are opposite to slots 12 in a cover plate 11 on the side of the wall box 8, thus allowing insertion of the handle, but on moving the switch to the on position shown the keys 9 are behind the plate 11 and the handle cannot be removed. In this position a flange 13 on the handle overlies a curved portion 14 of the lid and prevents the lid being opened.
