This BitSwitch allows a signal to be set from a control panel.  If the signal has been set RED when the train detector is activated the train will slow to a stop using CV4 braking momentum.  When the signal is manually set GREEN from the control panel the train will accelerate using CV3 momentum. If the signal is GREEN when the train detector is activated the train is not affected.

The Manual Signal BitSwitch operates in accordance with the schematic below.

Depending on the type signal being used two versions of this switch are available. 

The DCC-BitSwitch Manual Braking Circuit is designed to simplify the installation of a manually controlled signal.
Included with this special circuit is a magnetic reed switch to serve as the “TRACK DETECTOR”.
The “Signal RED & GREEN Buttons” are not included and should be momentary pulse switches.
The “POWER IN” can be supplied via AC, DC or DCC sources.  The “POWER IN” voltage will determine the voltage supplied the SIGNAL.  The “POWER IN” can normally be supplied using either booster output.

Power to the signal is:

"CONSTANT" Simple RED/GREEN lamps.

"PULSED" Twin coil motorized semaphore.
