Abstract

A steering indicator switch, for a road vehicle, including a body, a manually movable member, supported by the body for its angular movement relative thereto from a central rest position in a direction around a first axis to a first operative position, and from said central rest position in the opposite direction about a second axis to a second operative position, with said first and second axis spaced apart and parallel, first elastic means for pushing said member to said position of rest, central, ratchet means capable of retaining said member in said operative positions against the action of said elastic means, said ratchet means comprising first and second ratchet elements carried by the manually movable member and elastically biased towards its outside in opposite directions respectively, in contact with a first and second forms of ratchet respectively being provided said first and second ratchet forms on opposite walls respectively of the body, a pawl engageable with said first and second ratchet elements, said one being movable relative to the body between a retracted rest position and a position operative in protrusion in which, during use, the nail intersects the path of movement of a striker for cancellation of the associated switch that rotates with the steering column of the vehicle, said tab being movable, at least in said operative position, angularly with relation to the body in any direction from a central rest position, said nail being biased elastically towards its operative position, and also being resiliently biased towards its central position, and both the nail and said manually moving member portion co-operating which, in said resting position of said member or movable manually, they retain said nail in its rest position, retracted and that, in any of said first and second operative positions of said manually movable member allow said nail to move to its operative position in projection, the embodiment being such that during its use, when the ratchet finger is in its operative position, it is angularly deviated from said central position by said striker during the rotation of the steering column of the vehicle, serving the angular movement of the nail resulting from the movement in the direction of cancellation of the firing pin to cause the nail and the first or second ratchet element to cooperate to move the ratchet element against its elastic thrust and thus release said manually movable member for the return movement to said central rest position under the action of said elastic means, restoring such movement of the manually movable member the nail to its resting position retracted.
