Electrical switch

摘要

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.

主权项

1. An electrical switch, comprising:
the overcurrent tripping device including a first shaft that, in the event of the overcurrent situation, rotates from a first position into a second position and, through the rotation, indicates the overcurrent situation; and a thermal tripping device that, in the event of a thermal overload, switches off the flow of current through the switch, the thermal tripping device including a second shaft that rotates, in the event of a thermal overload, and rotates in the event of a rotation of the first shaft and initiates the switching off of the switch when the second shaft rotates, wherein the second shaft is nested within the first shaft such that the first shaft forms a sleeve around the second shaft.
