ABSTRACT:
A manually actuatable electrical switch assembly, employable as, for example, a turn signal and emergency warning switch assembly for automobiles, trucks or the like, has a main body or housing carrying electrically openable circuit means the opening of which is controlled by manually rotatable handle means selectively manually positionable to any of a plurality of selected positions to thereby open and close related electrical circuit means leading to associated sensory warning means; motion transmitting lever means, carried by an adapter body which is operatively secured as between the main body or housing and a cooperating vehicular steering column housing, is effective to cooperate with first abutment means, moved in response to turning of the associated vehicular steering wheel, to transmit a force to second abutment means, operatively carried by the handle means, in order to thereby be effective to at least at times move said handle means from a previously selected position to a position which might be considered as a null position; and escapement-like means are provided whereby the first and second abutment means can engage and move past each other without causing the handle means to move from a previously selected position if such handle means is manually held in such selected position.
