Modular Control Panel for 20mm Toggle Switches

🚂 Modular Control Panel for 20mm Toggle Switches

This modular housing system was specifically developed for controlling model railway layouts. It provides a clean and professional look for your control center and can be flexibly adapted to your needs.

In this example, the panel is used for the following functions:

• 3x On/Off Switches (top): Lighting control for various sectors (e.g., Almhöhe, Sbf, Oberegg).
• 4x Changeover Switches (bottom): Control of signals (Red/Green) without solenoid for the main station Neustadt Hbf.

🛠️ Features:

• Precise Fit: Optimized for standard toggle switches with 20 mm diameter.
• Integrated Cable Management: The undercarriage offers sufficient space for internal wiring, resistors, or small distribution boards.
• Large Cable Entry: A generous opening in the base allows for easy routing of cable harnesses from below the layout.
• Labelable: The flat surface offers enough space for label stickers or engravings (as seen in the photo).

📐 Technical Details & Print Instructions:

• Hole Diameter: 20 mm
• Mounting: The housing can be screwed directly onto the base plate or integrated into a frame.
• Recommended Material: PLA, PETG or ASA (for more stability).
• Support: Depending on the orientation, no or only minimal support is needed for the cable opening.
