How to Calculate an RC Debouncer for Mechanical Switches
Calculate RC components or software delays to debounce mechanical switches. Prevent signal noise and ensure clean digital inputs in your circuits.
Why to apply debounce circuits?
Mechanical switches and buttons often generate noisy signals when pressed or released. This tool helps you design a debounce circuit (RC filter) or select a software delay to stabilize your digital inputs. Enter your desired debounce time and get resistor-capacitor recommendations or software timing hints.
The formula is:
\[ debounce_{time} = 5 \times R \times C \]
