APPLICATIONS:
  • Molded jumper wires of crossovers, as they are sometimes called, are basically interconnection devices between points on a PC board.
  • Generally they are used for the following reasons:
  • Inability to connect two points on a PC board due to other circuit paths which must be crossed over.
  • An after-the- fact design change that requires new point connections.
  • Circuit tuning by changing point connections.
  • Optional feature applications.
