ABSTRACT:
A contact device for low voltage switch devices, includes at least two stationary contact bars with contact pieces, as well as at least one electrically-conductive contact bridge which is disposed in a contact bridge support and is movable by means of a spring force. In order to provide a good contact device wherein a weight and material saving is obtained, wherein simultaneously a switch-on impact of the contact is prevented and wherein a good adaptability of the movable contact pieces to the position of the stationary contact pieces is obtained, the contact bridge is made from a flexible material and a contact pressure spring for each of the two movable contact pieces is provided.
