Abstract
745,768. Retractive switches. ERBSLOEH, P. G. Nov. 28, 1953. No. 33083/53. Class 38(5) [Also in Group XXXVIII] A switch for a warning system in a vehicle (see Group XXXVIII) comprises a casing 44 secured to the steering column by means of a clamp 45 and carrying an operating stirrup 6<SP>1</SP> rigidly connected to a shaft 47 journalled in the casing 44. The stirrup is swingable within an angle defined by a stop member 57 (Fig. 9, not shown). A fixed contact 50 is fitted in an angle member 49 secured to the casing 44 by a connecting terminal 54. Insulating washers 52 and 53 serve to insulate contact 50 from the casing 44 which acts as the connection to a moving contact 48 mounted on the shaft 47 to co-operate with fixed contact 50. A spring 51 urges contact 48 to its position of rest away from contact 50. The base plate 46 is of insulating material and serves to secure the casing 44 to the clamp 45.
