# Switch Box

A printed two part box for the van's rocker switches: any mix of Contura II and round 25 mm rockers, with spare positions you open later.

[Open the configurator](index.html) · status: **draft**, version 0.1

## Settings

- **Switches:** positions, positions per row, a type for each position, engraved labels. Spares keep a 0.6 mm skin to cut out later.
- **Mounting:** cabinet face (front flange), wall (screw ears) or L-track (two studs). Wall and track can tilt the face up to 35 degrees. Wire exit in the bottom wall or the back plate.
- **Box:** depth, face thickness, hole clearance.
- **Fit test:** a small coupon with one Contura cut and one round hole.

## Build

Shell prints face down with no supports. Back plate prints flat. Press four M4 x 8 heat set inserts (5.6 mm bore) into the posts. Filament choice follows the kit; ASA or PAHT-CF suit a hot van better than PLA.

Wire with 1/4 in spades on Contura terminals and ring lugs on any post. The round rocker has its own 14 AWG leads and a 20 AWG black lead.
