Notes:

More on this clever device
en.wikipedia.org/wiki/Centrifugal_switch

*The oldest patent I could find was from 1926. But it seems to have been in regular use by then making me think variations are likely much older than that.

*The comment about "specifically the US" is about single phase power... Countries that have three phase power use 3 phase motors which don't need a kick start. We have both 120 and 240 in the US. The motor in this video is 240
