The enclosure for YEYY’s cyclical motor control board features pre‑installed mounting locations for limit switches, a start button, and a stop button.

The main board measures 90 mm × 60 mm, with the specific models and specifications for the limit switches and buttons detailed in Figures 5 and 6.

I’m using this board to build a tapping machine—as shown in Figure 2. Since there’s a 9 mm plate serving as the base, we’ve incorporated a 9 mm upper and lower limit switch. If these aren’t needed, they can easily be subtracted via Boolean operations.
