Summary

[edit]
Description
English: Switch bounce on a HP 54501A digitising oscilloscope. A latching switch was used, one end connected to 12V and the other end to the oscilloscope. The oscilloscope is set to trigger above 3V. As can be clearly seen the switch bounces between (hence the term, switch bounce) on and off several times for at least 1 millisecond after it is switched. The decaying waveform is due to the relatively large capacitance of the switch (a few nanofarads) compared to the relatively high impedance of the oscilloscope (about 1 meg-ohm.)
