Abstract
A brush vacuum cleaner having a safety shutdown of the drive via an overload brush roller torque detection. A mechanical triggering element via transmission elements actuates an electrical switch for the main switch to shut down the drive above a torque threshold. The switch is additionally connected in parallel by an external actuating element to an on and off position by a spring-loaded control element and a coupling element. Due to the control element, switching the switch into an off position due to overload is transmitted to the actuating element that can be adjusted into an off position. The control element is spring held in the on position in an arrangement for the engagement of the control element, where an unlocking can be set as off position by adjustment of the control element via the actuating element against the spring pressure.
