Abstract
The electric switching device according to the invention has at least one fixed and one movable contact (9 and 11, respectively), of which the movable contact (11) is influenced by a contact pressure spring (23) and is displaceable with the aid of a contact carrier (14) which is movable in relation to the movable contact. The electric switching device is provided with a magnetic circuit, magnetized by the current through the contacts, for increasing the contact pressure at high currents. The magnetic circuit comprises a core (25) which is fixed to the contact carrier (14) with the aid of the contact pressure spring, and an armature (26) which is rigidly connected to the movable contact (11).
