  • the arrangement of the connecting part also makes it possible to simplify the shape of the fixed contacts and of their supply part. These fixed contacts can extend in the same plane, just like the cursors. In this case, certain fixed contacts are offset relative to the supply part.
  • the sheets may have different thicknesses depending on the applications.
  • the supply part - fixed contact assemblies are very simplified and it becomes possible to attach at least two such assemblies in the form of conductive plates with possible folding, then after overmolding to separate them from one another by breaking for example connecting bridges. The number of parts to be handled is therefore reduced.
  • the arrangement according to the invention therefore provides numerous advantages and also makes it possible to simplify the cursors which may consist overall of rings of simple and robust shape.
