Circuit removes relay-contact bounce - 27-Nov-03 Issue of EDN 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,... [Design Idea by John Guy, Maxim

Circuit Simulates Contact Bounce - 05/08/97 EDN-Design Ideas The
circuit in Firgure 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. [Design Idea by Shyam Sunder Tiwari,
IGCAR, Kalpakkam, India] |

Switch debouncer uses only one gate - 30-May-02 Issue of EDN
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 by Steven Robertson, Anritsu Co,
Morgan Hill, CA] |
