Abstract
An explosion-proof electronic system. The system comprises a substantially explosion-proof enclosure, a disk that is free to rotate about an axis, where the disk is located within the enclosure, an optical sensor that is configured to sense rotation of the disk, where the optical sensor is located within the enclosure, and a processor that is coupled to the optical sensor and analyzes a rotation input from the optical sensor to control in part the operation of the electronic system.
