Custom made silicone mechanical push button

A custom silicone mechanical push button converts a finger movement into motion at the underlying actuation point. The available travel should fit the panel and supporting mechanism so the key is neither held down at rest nor stopped before it can perform its intended input.

Compare the button's resting height with the inside of the finished housing. Include the position of the underlying switch or contact and any locating feature that controls lateral movement. The silicone part should sit naturally without a web stretched around another component.

Check the assembled button from the normal user direction and from slightly off center. It should move without scraping the panel edge and return when pressure is released. Evaluate the completed control's response with its actual electronics or mechanism. During service, keep debris out of the moving clearance and inspect the flexible junction for tears. If closure changes the button feel, revisit the internal spacing rather than forcing the button repeatedly until a trapped section appears to free itself.
