Abstract
A solid-state switch for an external system includes a cover member, a first solid-state transducer, a second transducer, a microcontroller, a user feedback device, and a switching circuit. The first transducer is mechanically coupled to the cover member and configured to generate first signals in response to a perturbation at the cover member. The second transducer is configured to generate second signals in response to the perturbation. The microcontroller is configured to obtain first data from the first signals, second data from the second signals, and determine user inputs in accordance with at least the first data, the second data, and an operational state of the solid-state switch. The user feedback device is configured to provide feedback to a user of the switch in accordance with a switching behavior of the switching circuit. The second transducer is configured as a proximity sensor for detecting proximity of an object to the cover member.
