Hello, nlate
Buttons is futurlec.com $0.32 TACT006 Raised Tactile Switch, keycaps is $0.25 TACTWHT White Tactile Switch Button.
They saying about two versions of operating force: 160gf and 260gf
but shipping only 250gf, which is a little bit hard.
In future im planning to make buttons with CNC lasercut technology (like in Zvezda DJ controller)
