There are three buttons with a ~123mm span total, and 41mm spacing between the buttons where the 16ga stainless would need to flex.
What are the dimenstions/sizes needed to register proper flexion?
1. "41mm spacing" refers to the center-to-center distance of two adjacent buttons, right? What's the width(height) size of the buttons?
2. The press force value, do you have specific test standard?
