These large clicky switches are great for making finger-friendly pushbuttons that can connect to your Feather. You'll get three switches so you can use them for projects that need a lot of options
The switches have four legs, but there's only two halves to the switch. The two sets of pins are normally open (disconnected) and when the button is pressed they are momentarily closed.
So don't forget when using in the breadboard that the two rows across from each other will be connected on the inside of the switch!
Inside there is a round contact and two side contacts. a little round dome sits on top and then a plastic 'hat' that makes the switch. When you push on the hat, it clicks the dome down to touch the middle part and connects it to the side bits.
