  • Publication number: 20210393288
    Abstract: Provided is a system and medical device that includes self diagnosing control switches. The control switch may be slidable within a slot in order to control activation of some function of the medical device. Due to natural wear and tear of movement of a control switch, the distances along the sliding slot that correspond to how much energy is used for the function may need to be adjusted over time in order to reflect the changing physical attributes of the actuator mechanism. The self diagnosing control switches of the present disclosures may be configured to automatically adjust for these thresholds using, for example, Hall effect sensors and magnets. In addition, in some cases, the self diagnosing control switches may be capable of indicating external influences on the controls, as well as predict a time until replacement is needed.
