摘要

The arrangement has a housing provided with a lock bit (13), an unlocking device and an actuation device i.e. key accommodation part (20), where the unlocking device is provided with a coupling part. The coupling part is arranged between the actuation device and the lock bit. The coupling part is actuated with a control circuit by an electromagnetic or piezoelectric actuator. A lock cylinder (10) is connected to an upstream of the control circuit. The unlocking device is equipped with an electrical emergency opening device that is connected to the upstream of the control circuit.
