R16-504BD 16mm 押しボタンスイッチ（グリーン）

The square casing on top makes aligning it in my drill jig much simpler than with round bezels. Mounted firmly in the 16mm hole and the button action is crisp with a satisfying click. Perfect for my arcade button panel project.

Finally found a non-latching 16mm switch that fits snugly into my panel without extra filing—the square casing top is exactly what I needed. The green LED is bright but not blinding, and the click feedback is satisfyingly crisp.

The 4-pin configuration made wiring it into my project straightforward, and the square casing fits snugly into a standard panel hole. The non-latching action is crisp and satisfying to press.
