You Reply:wow, @sisumike. you are the best. i have been looking for both - the button as well as the wires/plugs. thanks much for the pointers. this helped me a great deal. i like the vandal resistant Off-Mom pushbutton and i bet it would look really nice with a cnc milled alu case. the one i am trying to finish up right now is a 3d printed, black ABS, kinda whimsical looking, fairly minimal und understated case with lasercut acrylic lid. i will share here and on tinkercad and thingiverse when done.
For a flat minimal look I am very intrigued by this button.
