Abstract
240,982. Cable Accessories Co., Ltd., Reeves, F. H., and Crawford, A. Aug. 30, 1924. Switch mechanism interlocking with lids.-The operating handle f carries a cam device e which co-operates with one end of a member a pivoted to the switch casing at b, the other end of the member a being connected by a. pin h and slot a<2> to the lid g of the casing. When the lid g is open as shown, the slot a<2> is in concentric, relation with the pivot pin i of the lid g and the member a is thereby held in such a position that the handle f cannot be operated to close the switch. When the lid g is closed, the weight of the member a causes it to rock counter-clockwise so that the pin h engages an extension a<3> of the slot a<2>, and the handle f can then be moved in either direction to close a circuit.
