Title: Improvements in switches for controlling turning signals on motor vehicles
IPC: B60Q1/42
Filed: 1948-04-09
Abstract: 652,055. Mechanical switches without quick action. ETABLISSEMENTS E. JAEGER. April 9,1948, No. 9981. Convention date, June 10, 1947. [Class 38(v)] [Also in Group XXXVIII]. A control switch for vehicle direction indicators is adapted to be operated by hand and automatically restored to the neutral position by frictional drive from the steering gear when the latter is straightened on completion of the turn. A casing 1 of insulating material is mounted on the steering column and carries a T- shaped member 20 pivoted at 21 and having contact fingers 27 and 31 which areelectrically connected by the strip 33. A coil-spring 36 is attached to ears 34, 35 on the pivoted member 20 and is under slight tension so as to frictionally engage the movable steering tube 3 against a portion of the periphery of which it is applied. A spring carried on the pivot 21 presses the member 20 such that finger 27 contacts a thin metal plate 8 connected by terminal 11 to the source of electric current. In the neutral position shown, finger 31 presses on insulation between thin metal plates 12 and 16 connected by terminals 15 and 19 to the left- and right-hand turn indicators respectively. The lower end of finger 27 normally engages a recess in plate 8 such that movement of the tube 3 does not affect the position of member 20. When it is desired to make a turn the arm 23 is manually moved in the required direction, thereby energizing the appropriate indicator. Movement of the arm 23 is limited by the ends of the slot 24 in which it travels and thus rotation of tube 3 to cause the vehicle to turn does not affect member 20 but results in slipping between tube 3 and spring 36. On reversing the rotation of tube 3 friction with the spring 36 restores member 20 to its neutral position where it is then maintained by the finger 27 entering the recess in plate 8.
