Abstract
A system including a calculator and a control housing including switches having a single stable position in an opened position and with a manual control member for the switches. The control member is of monostable type with automatic return into a rest position in which all switches are open. The housing includes: a single first switch controlling actuation of brakes and adapted to be closed upon an action on the control member in a first direction; a single second switch controlling release of the brakes and adapted to be closed upon an action on the control member in a second direction opposite the first direction; and a diagnosis circuit providing, according to the position of the control member, an analog information distinguishing between a system activated state in which one of the first and second switches is closed, a system deactivated state in which the first and second switches are open, and malfunction states.
