20x Silikon Gummi Einzel Tastatur Tastatur Carbon Pille Knopf Schalter Schlüssel PCB Halterung
5,95 €
These single buttons feature two flexible tapered protrusions - the principle is to make two holes in the PCB very slightly smaller than the widest point of the protrusion. You can stretch and elongate the narrow end of the protrusions to pull them through the holes, then when released they expand to fit in the hole tightly.
