Circuit Removes Relay-Contact Bounce - 27-Nov-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__ Circuit Design by Shyam Sunder Tiwari, IGCAR, Kalpakkam, India
Circuit Simulates Contact Bounce - 05/08/97 EDN-Design Ideas The circuit in Figure 1a simulates contact bounce of electromechanically and mechanically actuated electrical contacts. The circuit generates contact-bounce pulses for contact closing and opening. You can easily program the contact-bounce period and frequency through variable resistors. This circuit is useful for testing debouncing-hardware circuits and debouncing-software programs__ Circuit Design by John Guy, Maxim Integrated Products, Sunnyvale, CA |

Debouncing networks make reliable selector - 06/05/97 EDN-Design Ideas The expandable selector in Figure 1 consists of six switches, a HEX D-type flip-flop and two comparators with hysteresis and debouncing networks. The debouncing networks ensure that only one output of IC2 is high at any time, and you can expand this circuit using more switches and D-type flip-flops.__ Circuit Design by W Dijkstra, Waalre, The Netherlands

Switch Debouncer isolates input & output - 04/27/00 EDN-Design Ideas Modern programmable-logic controllers (PLCs) for automated process-control systems have either 16 or 32 inputs and accept ac voltages of 24 to 120V. A single circuit (a relay for isolation and an RC network with a Schmitt trigger to debounce signals to the processor) can debounce all the PLC signals in sequence. However, this approach slows real-time data processing. __ Circuit Design by Phill Leyva
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__ Circuit Design by Steven Robertson, Anritsu Co, Morgan Hill, CA |
