Operation overview
The light signal switch is developed to control a Maerklin* Hobby-light
signal. Using it with Viessmann*-signal kits is possible as well. The
Viessmann*-signal kits have to be modified, you can order the manual
from us or you can download it from our homepage.
The light signal switch has to be connected between the light signal and
an external change-over switch which switches between the two signals
("red" and "green"). Using a switching decoder to switch between the
two signals is possible as well. Push-button switches as used e.g. to
switch points are not suitabe to switch between signals. In exactly the
same way as in real life, the light signal switch causes the LED switched
off to fade slowly and the LED switched on to brighten slowly.
