  • the contact spring "minus” contacts the battery with three spring-loaded arms on the lower minus side. About a partial gilding and Mixkalotten a clean contact point is reached here.
  • An additional raised pedestal prevents the contact arms from sitting on the circuit board during a crash (drop test) and damaging the battery surface by compression. Through the pedestal, the contact arms can swing back freely.
  • the contact spring is soldered to the printed circuit board SMD (Surface Mounted Device). Over the length of the contact arms, the preload and the shape of the cap, the required forces and legislativenprossungen be set. Due to the mechanical arrangement of the two contact springs is also given a purely mechanical Verpoltik.
