ELM411 Debounce Circuit

The ELM411 provides all of the necessary circuitry to connect as many as three independent mechanical contacts to an electronic circuit. All mechanical contacts, whether from switches, relays, etc. will have inherent ‘bounce’ when they make or break a connection. Depending on the type of switch, thi.
