Circuit Removes Relay Contact Bounce - 11/27/03 EDN-Design Ideas: Advances in semiconductor technology have allowed ICs to replace many mechanical relays, but relays still dominate in high-current circuits that must stand off high voltages of arbitrary polarity. Contact bounce in those relays, however, can prove troublesome to downstream circuitry. One approach to contact bounce combines a relay with a hot-swap controller.....(design idea)

Switch Debouncer Isolates Input & Output - 04/27/00 EDN-Design Ideas:.....(design idea)
Switch Debouncer uses Only One Gate - 05/30/02 EDN-Design Ideas: The circuit in Figure 1 produces a single debounced pulse each time you press S1. Moreover, the circuit uses only logic power from the remote pull-up resistor, R2. You can use the circuit to detect when a key is pressed in a nonenergized device, such as a device in a system that's just coming up from standby…..(design idea)
