Abstract

376,888. Switch covers. HEATH, H., 22, Beaufort Avenue, Washwood Heath, and BILL, R. W., 1, Somerset Road, Handsworth Wood, both in Birmingham. May 16, 1931, No. 14517. [Class 38 (v).] The sliding lid A of a switch box is interlocked with the switch mechanism so that the lid cannot be opened when the switch is " off " and the switch cannot be moved "on" until the lid-is closed. For this purpose the switch handle E may have a projection F which can move into a recess H in the lid A when the lid is closed. Alternatively a cam on the opposite end of the switch spindle may engage a projection or notch on the lid.
