  • Patent number: 8319131
    Abstract: A device is disclosed for switching an electrical switch on and off, with a drive shaft and an output shaft. The drive shaft and the output shaft run transversely with respect to one another and interact in such that a rotation of the drive shaft entails a rotation of the output shaft, the drive shaft being rotatable between an ON position and an OFF position, and the output shaft being rotatable between a switch-on position and a switch-off position. The output shaft is connected to the switch which can be switched to the switch-on and the switch-off position as a result of the rotation of the output shaft. The drive shaft and the output shaft are connected to one another via a displaceable sliding element which, during the rotation of the drive shaft, is displaced, and the output shaft is rotated by the sliding element in the course of displacement.

  • Publication number: 20100326805
    Abstract: A device is disclosed for switching an electrical switch on and off, with a drive shaft and with an output shaft. In at least one embodiment, the drive shaft and the output shaft running transversely with respect to one another and interacting in such a way that a rotation of the drive shaft entails a rotation of the output shaft, the drive shaft being rotatable between an ON position and an OFF position, and the output shaft being rotatable correspondingly thereto between a switch-on position and a switch-off position. In at least one embodiment, the output shaft is connected to the switch which can be switched on into the switch-on position as a result of the rotation of the output shaft and can be switched off into the switch-off position by rotation.
