Switch, In Particular Load Breaking Switch

A switch is disclosed. In at least one embodiment, the switch is a load breaking switch including a rotor which is embodied in particular as a switch shaft segment, and a contact arm which is pivotally mounted in the rotor and is pivotable between an ON and OFF position about an axis of rotation and at the free end of which is a contact piece which is pivotable together with the contact arm and is in contact with an opposite fixedly arranged contact piece when the contact arm is in its ON position. In at least one embodiment, the current flows through the switch via the contact pieces and the contact arm, wherein the contact arm is pivotable into its OFF position when the current flowing via the contact pieces exceeds a value, in particular the rated current value or an overload current value. In order to provide a load breaking switch which is simple in terms of its construction and at the same time has a high current-carrying capacity, it is proposed in at least one embodiment that a magnetizable area is spatially arranged inside the rotor in such a way that the current flowing through the contact arm in this area induces a magnetic field which in turn exerts a torque on the contact arm.
