SparkFun COM-09190 Momentary Push Button Switch – 12mm Square
This is a standard 12mm square momentary button. What we really like is the large button head and good tactile feel (it ‘clicks’ really well). This button is great for user input on a PCB or a good, big reset button on a breadboard. Breadboard friendly!
Neil Green –
A really good-sized, satisfyingly clicky button perfect for breadboard projects.
Shane –
I was expecting the smaller buttons – These are much better quality than the buttons you get in some of the Arduino kits.
