Abstract

861,512. Switch covers. PRESSED STEEL CO. Ltd. Dec. 3, 1959 [Oct. 22, 1958], No. 33728/58. Class 38 (5). [Also in Group V] A switch-box cover 11 of plastic material having side-walls 12, 13, 14, 15, a back wall 16, and a rim 17, is produced by a vacuum-forming operation between dies carrying complementary knife-edge parts which form sharp depressions 18, 19 which are later cut around with a penknife to produce cut-outs a to permit the passage of electric cables.
