The invention relates to an emergency off-switch (10) for triggering an emergency switch-off function for the safety-related switching off of an electrical device (12), comprising an actuation element (34) and at least two electrical contacts (40, 42) that can be connected to one another via a contact bridge (38), wherein a position of the contact bridge (38) is influenced by the actuation element (34), such that the electrical contacts (40, 42) can be opened and/or closed. The emergency off-switch (10) also has an active operating state in which the emergency switch-off function can be triggered by moving the contact bridge (38), and a passive operating state in which the emergency off-switch is functionless. The emergency off-switch (10) further comprises a visualisation device (56) having at least one first and one second display state, wherein, in the first display state, the emergency off-switch (10), in particular the actuation element (34), is visually highlighted, and in the second display state, the emergency off-switch (10) is neutrally represented. The visualisation device (56) is also designed to adopt the first display state in the active operating state, and to adopt the second display state in the passive operating state. In addition, the emergency off-switch (10) includes a monitoring unit (60) that monitors whether the visualisation device (56) is in the first or the second display state, in order to trigger an action, in particular the emergency switch-off function, accordingly. |
