Must admit I've always though this is an oscillation created by the inductivity and capacitance of the circuit, never though of it as an actual mechanical switch bouncing off the other contact. Shouldn't a spark form and short-circuit the mechanical contacts even if they bounce around a little?
- TheSpiceIsLife 7y agoTechnology Connections has a good video on switches sparking, or not, https://youtu.be/jrMiqEkSk48 https://youtu.be/jrMiqEkSk48
- pjc50 7y agoArcing is only present if there's a significant amount of current flowing, which there isn't in switches used for user input.
