When ordered in pcb these can be used to replace the buttons on steam decks. They are also good for any carbon padded button you would like to add. Or get a conductive finger piece & ta daaa touch buttons. They are standard "4 pinned" format tactile button replacement. These are perfect anything you would like to make in high use high repairability situation. These are basically meant to be replaceable. I made these originally due to my steam deck giving me tennis elbow. The activation force was too high on tactiles so I made these & replaced the oem buttons on the steam deck. I have also since modeled & created my own controller with these & a 3d printer pen. So these are a powerful little tool when prototyping or even just adding custom gear.
