Abstract
A method of switch detection is disclosed that comprises, enabling a low power mode on a switch detection device, activating a first detection circuit for detecting, at a first expiration of a first polling time interval, a first switch state of a first switch having a first priority level, the first switch state including one of a first open state and a first closed state, comparing the detected first switch state with a prior first switch state, and activating a second detection circuit for detecting, at a second expiration of a second polling time interval, a second switch state of a second switch having a second priority level, the second switch including one of a second open state and a second closed state, and the second polling time interval being greater than the first polling time interval, and the second priority level being different from the first priority level.
