r they called centrifugal clutches even though they have different design of opperation.
Yes.
The one on the left pits centrifugal force against a spring and the one on the right pits centrifugal force against the tension of the metal. Either way, centrifugal force causes a inner part to move outwards, increasing the radius, till it makes friction contact with something else to make it move once the rpm is sufficient to generate enough CF.
