Abstract
An electromagnetic switching apparatus including a housing, movable contact elements mounted on a plurality of contact bridges in the housing, electrically-connected fixed contact elements disposed on both sides of the contact bridges adapted for contact and electrical connection with the movable contacts and the contact bridges, and electrical insulation means for interrupting the electrical connection between the fixed contact elements and the contact bridges in two terminal positions of the contact bridge carrier. The improvement comprises at least one end of the contact bridges extending outwardly beyond the area of contact between the movable contacts and the fixed contacts. The electrical insulation means are movably supported in the switching apparatus housing so as to be operatively engageable in at least one position with the extended ends of the contact bridges for interrupting the electrical connection between at least one of the contact bridges and the fixed contact elements.
