순간 온-오프 푸시 버튼 스위치 (블루)

Was a bit stiff to press at first but after a few cycles it loosened up nicely and has been working flawlessly with my Arduino setup. The blue actuator looks sharp against the black body.

The 7mm panel cut-out was spot on, so it snapped into my project box without any fiddly filing. I've clicked it a few hundred times testing my prototype and it still feels crisp, no wobble or sticking.

Perfect size for my small breadboard project, the 7mm cutout was exactly as described and it clicks firmly. For less than a dollar you get a solid momentary switch that handles 125V fine for low-current use.
