Support material is designed into the print to minimize support material used. See Post-Printing instructions.

This is designed with support structures for bridging. There is a thin bridge layer under the overhang for the holes to print on. After printing this layer is removed. The thin triangle support near the hole on the end can be cut off.

Note the switch orientation. In this picture the switch the wide spaced terminals are at the bottom. Before you insert the switch into the assembly, note the location you plan to install the assembly and position the switch so ON is up.

Wiring so switch light is on when power is on:

Solder a short jumper from the fused Line terminal to one side of the switch. Solder the jumper to on of the terminals that are spaced closest together. Solder a wire to the wide spaced terminals, on the same side. This wire will go to the L terminal (Line) on the power supply.

Solder a short jumper wire to the other close spaced terminal. This wire can be a smaller wire because it just caries the load of the internal switch light. This wire will connect to the unfused terminal. In addition use a second wire, solder both to the unfused terminal. Connect this second wire to the N terminal (Neutral) of the power supply.

Solder a ground wire to the ground terminal and connect this to the ground terminal of the power supply.
