AtomSoftTech has a convenient little board to make it easy to connect a tact switch to a breadboard:
What is it?
A button you can be glad to have.
Why did you make it?
There isnt a small breadboard-able button out there with the features on this one.
What makes it special?
You have a selectable Pull-Up or Pull-Down and selectable High Output or Low Output. Using simple solder jumpers you can select between Pull up or Pull Down and what is the output of the button. All in a TINY PCB takinng almost no space on your PCB. No need to wire anything its breadboard friendly. Connects to the power rails and data side as well
