ABSTRACT:
An actuator unit includes a base actuator and an additional actuator, via which a useful circuit can be opened and closed. Given proper functioning, the base actuator can be activated by supplying electric energy and deactivated by not supplying electric energy. The additional actuator can be deactivated by supplying electric energy and can be activated via manual operation. A control unit deactivates the additional actuator only when an actual activation state of the base actuator differs from a desired activation state of the base actuator.
