Ignition key for Demag AC80-1

The ignition key 420 447 12 serves as the primary interface for starting the engine and energizing the main electrical circuits of the Demag AC80-1 all-terrain crane. By engaging the ignition switch, this component allows the operator to initialize the machine systems and gain control over the crane functions. It acts as a security measure to ensure that only authorized personnel can operate the equipment, preventing unauthorized use of the crane on site.

This specific part is compatible with the Demag AC80-1 model. It is engineered to interface directly with the crane's ignition switch assembly to ensure consistent contact and reliable starting performance. Proper maintenance of the ignition key is necessary to avoid electrical contact issues or starting failures that could lead to equipment downtime.

In heavy machinery, ignition keys are used to complete the circuit required to power the starter motor and activate the control console. They are often part of a broader security system that manages access to the machine's operational controls, ensuring that the ignition sequence is only triggered when the correct key is inserted into the ignition lock.
