Abstract: An electronic device includes a seal compressed between a moveable structure and a support. A retainer maintains seal compression in a first direction absent force exerted on the moveable structure. However, the retainer allows increased seal compression by moving in a second, opposing direction when force is exerted on the moveable structure. A force sensor (positioned internal to the seal) is influenced by movement of the moveable structure in response to the force and a signal received from the force sensor indicates an amount of the force. By maintaining the seal in compression but allowing further compression, the seal can hermetically seal the electronic device against contaminant entry without adversely impacting detection of the amount of force.
