1. An emergency stop switch, comprising:
a switch mechanism with a manually operable switch and with a first contact element which is operatively connected to the switch, wherein the switch is configured, upon actuation of the switch, to bring the first contact element into contact with a second contact element to trigger an emergency stop function, and
a cable pull mechanism with a switch tongue guided in a switch tongue guide, wherein the switch tongue is configured to be connected to a first end of a cable, wherein a switch tongue spring preloads the switch tongue during operation in a direction away from the cable, wherein the cable is connected at its second end to an equalizing spring,
wherein the first contact element is operatively connected to the switch tongue, wherein the switch tongue, when the preloaded cable is pulled, is guided in the switch tongue guide in the direction of the cable, opposing a spring force of the switch tongue spring, and brings the first contact element into contact with the second contact element in order to trigger the emergency stop function by means of the cable pull mechanism.
