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) |

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