摘要

1. Device for controlling a motor which is driven by a pressure medium and is designed to control the blocking members (19, 20, 24, 25) controlling the supply and discharge of the pressure medium via a switching rod (7), wherein there is provided between the switching rod (7) and the blocking members (19, 20, 24, 25) a snap mechanism having a rocker switch (8, 9, 10) which has a spring-loaded telescopic rod (9', 10') hinged to a rocker lever (3) and to a further pivotally mounted lever (5) hinged to the switching rod (7), which telescopic rod serves simultaneously as guide for the spring (8), and wherein snap-in catches (13, 14) cooperate with the rocker lever (3).
