Single-Chip Switch Debouncer
Contact bounce is an age-old problem with all types of pushbutton switches and keypads that are connected to digital components. The measures that are used to deal with the repeated closing of the contacts when the switch is first activated include RC networks, flip-flop circuits and software routines.
