Yes it does. I had to increase the switch debounce time (“buttonInterval”, was 100 now 400) to prevent double hits when the button was pressed. Measuring with my oscilloscope I observed the little through-hole buttons on the boards don’t contact bounce at all. However the microswitch under the big button on my table has a debounce time of about 3ms. No trouble with ringing or noise even though all the switches are wired in parallel.
