Patent ID: 8610522

Claim:
An electrical switch for switching an electric current, the switch being insertable into a switch holding device, the switch comprising: a locking device configured to, in the event of an overcurrent, move a locking element of the locking device to a position which mechanically locks the switch in the switch holding device, the locking device including, a yoke, and a moving armature element configured to, in the event of an overcurrent, be moved in the direction of the yoke by the magnetic force caused by the overcurrent, the moving armature element forming the locking element or being connected indirectly or directly to the locking element; and a conductor element, configured to conduct the current to be switched and arranged between the yoke and the armature element such that a current flowing through the conductor element causes a magnetic flux around the conductor element in the magnetic circuit formed by the yoke and the armature element.
