<p>The mechanism includes an operating element movable lengthwise from a neutral position on two opposite directions. Contact surfaces interact with the control element operation interacting with the latter. Two contact surfaces (15, 16) are provided on one side of the operating element (10), so that when the operating element (10) is moved from the neutral position, one of the surfaces (15, 16) presses on the control element (21). Only one such contact surface (17) is provided on the opposite side of the operating element.</p> |
