Little clicky switches are standard input “buttons” on electronic projects. These are just like our Colorful Round Tactile Button Switch Assortment, but already assembled onto a PCB – they even have a pull-up resistor installed! The pins are normally open (disconnected) and when the button is pressed they are momentarily closed.
Each button comes with a candy-colored round cap snapped on. You get one of each color– blue, white, yellow, red, and black.
Best of all, each button board comes with a JST-PH 2mm connector and a matching JST PH 3-Pin to Male Header Cables – 200mm, so wiring up is a cinch. Simply plug the cable in, then use the black wire to connect to your microcontroller/microcomputer ground, white wire to the input signal pin and the red wire to your power pin (3V or 5V) if you want to have the pull-up resistor activated.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
