ABSTRACT:
A switch de-bouncing device includes a majority counter that counts samples generated by a sampler sampling a switch output where a counter value is incremented for each sample indicating a first switch state and decremented for each sample indicating a second switch state of the switch. A controller determines that the switch is in the first switch state when the counter value is above a first state threshold and is in the second switch state when the counter value is below a second state threshold.
