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 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)
