20 Pairs Push Buttons With Caps - 4x4mm Micro Switches For Arduino, ESP32, Raspberry Pi DIY Projects

About This Product

Hey makers and tinkerers! If you're constantly building electronics projects, these push button sets are gonna be your new best friend. You get 20 complete pairs - that's 20 buttons AND 20 matching caps in each pack. The buttons themselves are that perfect 4x4mm square size that fits nicely on breadboards and PCBs. What's really cool is they're rated for at least 500,000 clicks, so these aren't some flimsy buttons that'll give out after a few months of use. Super versatile too - work with pretty much any microcontroller you're likely to use like Arduino boards, ESP32, ESP8266, Raspberry Pi, whether you're running 5V or 3.3V systems. The caps snap on securely and come in different colors usually, which is great for color-coding your projects. I've used these for everything from simple LED controllers to more complex IoT projects - they've got that satisfying click feel without being too loud or stiff. The manufacturers even provide tutorials for Arduino and ESP32 setups, which is super helpful if you're just getting started with electronics. The pins are standard spacing so they plug right into breadboards without issues. Having 20 pairs means you can mess up a few while soldering and still have plenty left, or use them across multiple projects. Seriously, if you do any kind of DIY electronics work, having a stock of these reliable push buttons is just essential workshop inventory. They're that perfect component that bridges the physical world with your digital creations!
