Abstract
A switch has at least one fixed and one moving contact located on a contact arm. The fixed contact is connected to a loop-shaped conductor segment, such that when current flows through the conductor segment, there is an electrodynamic magnetic force which acts on the contact arm. The force, above a specified current intensity, results in an opening movement of the contact arm. To open the moving contact more rapidly and in a simple manner the loop-shaped conductor segment is realized so that it is wound in a coil shape, and consists of at least two turns, and that the coil axis of the coil segment runs perpendicular to the longitudinal axis of the contact arm.
