SpletUsing mechanical switch products for signals gives a bounce effect that may cause short periods of unstable signal for an electronic circuit. Würth Elektronik switches have a bounce time of up to 10 ms, which should be considered, depending on the application. Therefore, the proposed filter in figure 7 can help to reduce this phenomena.

SpletHistory of the Legacy Switch Since the advent of the microprocessor and microcontrollers the propensity of the mechanical switch to "bounce" has proved to be a design problem for hardware and/or software designers that nearly always must be dealt with. The Electric Snap Switch was designed and patented in 1884 by J. H. Holmes to ease the SpletActuate the switch several times, and measure the length of "bounce zone", either by eye, or using the scope cursors.

Splet06. jun. 2024 · The problem of switch bounce was also solved in firmware so that the same pin had to remain high for a predefined time before it was accepted as valid. The code was called every 10mS and a counter incremented if the same pin was high. When the counter reached a predefined value, in this case, 10, the button press was considered valid. ... When working with microcontrollers, we can deal with switch bounce in a different way that will save both hardware space and money. Some programmers do not care much about bouncing switches and just add a 50ms delay after the first bounce. This will force the microcontroller to wait 50ms for the bouncing to … Prikaži več What is switch bounce?
