ABSTRACT:
An emergency switching apparatus is provided having an operating button which keeps the trace of its actuation and controls an electric switch.
The switch is struck by a piston which is itself driven by a spring which is loaded by the longitudinal movement of the button, and which is freed by the retraction of the latches, having, on the one hand, an antagonistic effect to that of the spring and, on the other hand, an action latching the button when these latches have ridden over a projection on which they were bearing beforehand.
