John B. ★★★★★ Oct 22, 2026

The square casing fits perfectly into my panel’s 16mm hole without any wobble, and the red button has a satisfying click. I’m using it as a reset switch for a microcontroller project, and the non-latching action works just as expected.

Alexander ★★★★★ Oct 21, 2026

The 4-pin layout made wiring this into my control panel straightforward, and the red LED is bright enough to see in daylight. Pressing it feels solid with a clean click, and the square casing gives it a neat, professional look once mounted.

Mounted the square bezel perfectly into a 16mm panel hole on my arcade controller, and the red button has a satisfying click. The non-latching action works great for momentary inputs.
