The invention relates to a console and a safety console having dual-stage functionality. The console has a key and a contact plate. According to one exemplary embodiment, the key has a dual-stage safety shutdown mat on which electrically conductive layers are located. The contact plate has two contact arrangements having electrically conductive safety contact elements and key contact elements. The console is configured to connect the electrically conductive safety contact elements and key contact elements. The console is configured to connect the electrically conductive safety contact elements by means of the safety contact layer in an inactive state, thus continuously monitoring the presence and active contact state of the key via a safety switch. In an active state, the key is configured to also connect the key contact elements via the key contact layer on the safety shutdown mat such that the activation can be registered by an evaluation circuit. |
