Bouncing

When you move a physical slide switch, the circuit opens and closes tens or hundreds of times. This phenomenon is called Bouncing.

Wokwi simulates switch bouncing by default. You can disable the bouncing simulation for individual switches by setting their “bounce” attr to “0”:

{ "bounce": "0" }
