Abstract
An electrical switch is disclosed, especially an electrical circuit breaker, including an overcurrent tripping device which, in the event of an overcurrent situation, switches off the flow of current through the switch; and a thermal tripping device which, in the event of a thermal overload, switches off the flow of current through the switch. In at least one embodiment, the overcurrent tripping device includes a first shaft which is disposed such that, in the event of an overcurrent situation, it is rotated from a first position into a second position and thereby indicates the overcurrent situation; and the thermal tripping device includes a second shaft which is disposed such that, it is rotated in the event of a thermal overload and is also rotated as well in the event of a rotation of the first shaft and when rotated initiates a switching-off of the switch.
