Digital Command Control (DCC)

I have provided a number of Digitrax throttles to members of the HOtrak club members. In order to help perserve battery life I have installed a small switch that increases time between battery changes.

Here is how I install the switch in the throttle.


Tools required to install the mini switch


The hole cut in the case to accept the switch


The orange cut and soldered to the switch. (note one leg of the switch is cut off as it is not needed)


The finished product



I also do decoder installs, here is an example of one.
