  • Hi Takao,

    You could try meeting those vias like you have pointed out and then attach the mechanical switch with a capacitor that is tied to ground. When the switch is open the line is simply open, when the switch is closed the capacitor is introduced and simulates the load that your finger is applying.

    Best Regards,
