Add an Auto Switch plus a Selector Switch to a PCP in a Box
Jim Exler, Nampa, ID August 31, 2020
Here is a series on 3D printing a box for the NCE Power Cab PCP panel and adding an Auto Switch and selector switch. See below to get the stl files for the printed parts.
First, the basic box with the Auto Switch mount and relative to the PCP panel.

| The only modification to the NCE components was to cut the traces to the TRACK connector on the PCP to allow the Auto Switch and selector switch to be between the PCP and the output. The picture shows the cut in the traces and wires to feed the Auto Switch soldered in the empty holes just above the left hand cut. Additional wires (red and white) were added to connect from the selector switch to the TRACK connector. |  |
| Next is the completed wiring before stuffing it in the box |  |
| The front of the finished unit | The rear connectors |

| Another option is to make the cover with a bracket for the Auto Switch. This means that the cover plate holds all the components and wiring so it can be used either with a box (no bracket inside) or as a fascia mount or home brew setup without the box. Here is a picture of the cover model from the back side showing the bracket . The function is exactly the same, only the method of mounting the Auto Switch is changed. |
