Functions
The S88 AC decoder registers and stores in memory elec-
trical contacts when momentary or continuous switches
connected to it are activated. Typical momentary contacts
are the Märklin circuit track or reed contacts. An example
of a continuous contact is the Märklin H0 contact tracks. All
switching contacts used with the S88 decoder must switch
to ground (brown connection) in the Märklin Digital system.

This ground connection can also be made on the track
detection module (socket marked with –).

cally.
