ABSTRACT:
An emergency off switching device for disconnecting an electrically operated machine from a circuit including a plurality of operated machines, includes a housing attached to the machine against which an externally accessible actuator cap is held in an axially movable arrangement, a contact switch accommodated in the housing which is closed when the switching device is in the non-actuated condition and by means of which the machine is electrically connected to the circuit, and a driver sleeve supported against the inside of the housing that is connected to the actuator cap with the free end of the driver sleeve opposite to the actuator cap facing the contact switch and disconnecting it from the circuit in the actuated condition, wherein a monitoring signal is generated when the switching device is in the actuated condition, to ascertain which of a plurality of the switching devices has been actuated.
