ABSTRACT:
A switching device, capable of being applied to the steering column of an autovehicle is described. The device comprises a sleeve which is provided with a front seat for housing one of the releasing pawls. The releasing pawl is capable of engaging with a shaped sector formed in an annular body operable by means of a radial lever connected to the steering wheel. The shaped sector presents a substantially concave central portion delimitated by two tooth raised portions and two nearly flat side portions. The annular body supports a resiliently biased contact plate and is provided with a cylindrical seat in which is housed a resilient pin. Near the annular body is located a disc structure on which are arranged three fixed contacts having suitably sized contacting surfaces. The fixed contacts are connected to the contact plate by slightly rotating the annular body. The device permits to avoid a double operation for each signalling maneuver.
