What is the difference between spring interlock and magnetic interlock?

  • Mechanical safety switches with spring interlock are interlocked when there is no power applied to the coil. This is safe guard locking.
  • In the case of mechanical safety switches with magnetic interlock, the interlock is active when power is applied to the coil. This is process guard locking.
