  • Patent number: 4849587
    Abstract: An actuator (26) operates tappets (24, 25) of two switches (21, 22) each controlling one of the directions of operation of the motor. The actuator (26) is guided in a lateral direction (WW') between two active positions in each of which it may then be depressed, causing one of its bosses (55, 56) to actuate the corresponding switch (21 or 22). Flexible lugs (34, 35) return the actuator (26) to an intermediate position in which depression is prevented by a fixed pin (52) cooperating with a projection (51) of the actuator (26). The control box facilitates changing from one direction of operation to the other while avoiding rapid switching, harmful to the motors.
