Cover only half of the untakt path, a1no according to the example chosen above, only about 8 mm. However, this is the fourth part of the contact path to be covered in known devices of a type of contact and is a significant reduction in merging by taking into account the invention and the forces required to move the movable contacts are smaller. Lamit results in a lighter 39 i, -, # - t eirl further lead: OKmal der '#: rfindung, 4 that the movable contacts in uer t-count of the remaining contacts are guided almost in a straight line and the contact surfaces of the peot contacts with the movement belts -of the moving contacts enclose an angle less than 90o. With a given contact spring force, the size of which is limited for structural reasons, a higher contact force is achieved and, moreover, only a small current loop is formed so that the continuous contact according to the invention can carry high short-circuit currents.

The movable Tcontacts are made by means of specially shaped curves of a Zurvenachelbe connected to the movable tegt. Actuated via a cam roller, the gradient is ger Zurven low and can therefore curve. Rolls with a large diameter, advantageously in needle-bearing cure rolls, - are twisted * i, old-rrx int it is possible due to the - small forces after the invention A r eitiziaen F,> urven2,91, le, and only a single curve of a curve body to with one but Im! e61le three-pheolos instead of sixov what with bokmnnten cleaning devices - only droi Mad that hereby a 'saving of expensive' pre-work can be done. There is a constructive limit to the size of the contact springs and the practically achievable Zontact spring force is not great. enough to give the necessary bench acceleration for the rare switchover, especially with regard to the flow resistance in the switch31 of the Vanze of the movable zoom.
