Design Notes

• For shutter half-press detection, choose lower force (120–180 gf) with shorter travel for precise thresholding and minimal bounce.
• Ensure mechanical stack-up allows perpendicular actuation to maximize life and tactile consistency.
• Implement ESD protection at the PCB level near the switch node for system compliance.
• Avoid overtravel beyond specified limits to protect dome integrity.
