3.1. 3.1.Switching behaviour of switching links with flywheeling diods
Normally magnetical switching links are switched on simply by connecting them to 24V DC. In the
diagram shown here, this is done at the time of 0ms. The inductivity causes a slow establishing of the
magnetic field and therefore a slow establishing of the magnetic force. At the time of 17ms the
magnetic force is established as far as it is able to antagonize the spring's force. Now the switching
movemeent is initialized. This is finished at 41ms. At the moment of 50ms the procedure of
switchingboff begins. The built in flywheeling diod causes a flywheeling voltage of -0.7V DC so that the
flywheeling current de-establishes the magnetic field slowly. At 71 ms, the spring's force is greater than
the magnetic force, so that the switching-off movement is initiated, which finishes at 95ms.
