What features would you look for on the switches you purchase for this design?

When purchasing switches for a design, I would prioritize features such as reliability and longevity, ensuring they can handle the required number of cycles. Additionally, I would look for switches with appropriate actuation force and tactile feedback to enhance user experience. Compatibility with the intended circuit design, including size and mounting options, is also crucial. Finally, considering the environmental conditions, I would opt for switches with adequate ratings for dust and moisture resistance.
