Abstract
A key (1) having one end (6) secured to a yoke (7) mounted in a casing (2) to turn between a position in which the key is retracted inside the casing and a position in which the key is extended, and a control pushbutton (17) mounted in the yoke to be constrained to pivot therewith, and to slide between an extended position for blocking the yoke in which the pushbutton possesses at least one stud (25) received in a notch (26) of a portion of the casing, and a pushed-in position for releasing the yoke to pivot, in which position the stud escapes from the notch, a spring (18) being interposed between the casing and the control pushbutton to urge the yoke resiliently towards the extended position and the control pushbutton towards its blocking position, the notch being formed in a washer (13) that is fitted in said portion of the casing, and the washer being harder than the casing.
