Abstract

779,272. Impact-operated switches; switches held set and freed mechanically. GENERAL ELECTRIC CO., Ltd. Oct. 12, 1955 [Oct. 12, 1954], No. 29411/54. Class 38(5) [Also in Group XI] A switch, intended for mounting in and controlling an aircraft emergency lamp, comprises a ball 18 normally located between movable and fixed supporting members 19, 17 respectively, the former being spring-loaded and carrying a contact disc 22 which moves into engagement with contacts 25 when the ball is displaced by mechanical shock or by a push button 29. The contacts 25 are carried by a slidable reset member 23 which when moved by a button 24 lifts the ball on to the concave end of member 17 and raises member 19 so that it again engages the top of the ball when the button 24 is released. The spring 21 acting on member 19 bears against an adjustable bushing 20. The switch is mounted in a housing with a transparent cover together with a battery and two bulbs.
