6.5. Connecting the switching input

The switching input switches against decoder ground and can therefore
be connected to all (external) circuits that can be used to establish a
ground connection. It is possible, for example, to connect reed contacts
or Hall sensors which establish the ground connection as soon as they
enter the magnetic field of a permanent magnet.
Connection of a reed contact
You can use both normally open contacts and changeover switches
(changeover contacts).
!
Note: The glass bulbs of reed contacts are sensitive to
mechanical damage!
Connect reed contacts to the switching input and the ground
connection of the decoder (GND). Reed contacts are not polarized, so
you can assign the two connections as you wish.
