  • a contact set is by only two interacting contact springs are formed, each by an independent Drive is movable. Their contact heads are arranged on a center line of the relay. These contact springs are positively guided by the comb. Both combs must each be moved in opposite directions. Reach these contact sets a double distance between the contact heads, however, they can not Serve circuit safety. If welded contacts are not loosened through this welding are both combs and therefore all contacts blocked. The position and design of the drive with anchor and comb is not shown.
  • a positively driven relay is a relay in which the Contacts with a common drive-related movable comb are positively guided and in which at least one working contact and a break contact is provided.
  • Forced management means that one at a time Contact element is present at a fixed stop and one with this contact element cooperating movable contact spring engages in the comb so that it is necessarily moved with the movements of the comb. This ensures that if a contact welds, either the welded contact is torn apart, or the comb can not be moved and therefore the other contacts, thus also the rest contact, in the one given by the welding Have to remain in position.
