  • a second magnet is provided in the magnetic lock, wherein the first magnet and the second magnet exert a force on each other.
  • preferably permanent magnets are used, but there are also magnetizable materials used as a magnet, if the same effect is achieved with these.
  • the bolt is pulled together with the magnet due to this force in the locking position. This results in a space-saving and safe execution of the magnetic lock. Not only a dynamic pulling is included, but also a static holding the bolt or driver.
