Class 79(5) [Also in Group XXXVII] The ring A of a steering wheel is formed with a groove ASP1/SP extending along its entire inner circumference, the groove having a contact element C extending therearound. Insulating elements P having contacts CSP1/SP are mounted in the groove and are normally urged to the centre of the wheel, i.e. to the left in Fig. 1, by a spring M threading the elements P. The circuit, e.g. of the horn, may be completed by engaging contacts C, CSP1/SP by radially outward pressure on any of elements P by the driver's fingers.
