Abstract

427,004. Snap-action switches for battery lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, TURNER, H. C., and DAVENPORT, A., c/o Salford Electrical Instruments, Ltd., Silk Street, Salford, Lancashire. Nov. 2, 1934, No. 31508. [Class 38 (v)] [See also Group XI] An electric cycle lamp has a metal casing 1 provided with a removable lid 3 to which is riveted a leaf spring 14. A spring terminal 10 of the battery 8 normally rests against an insulating member 12 carried by the lid. An operating member 15 sliding in a collar 16 carries a contact piece 17. In the off position shown, the spring 14 biasses the contact 17 to the right. On pushing the knob 18 to the left, the contact 17 slips past the curve of spring 14 and is then moved rapidly to the left to complete the circuit between terminal 10 and spring 14.
