Abstract
Abstract A spring suspension system for a seismometer for suspending one body relative to the second body including three resilient leaf cantilever springs each including two adjacently positioned leaf arc segments extending approximately 120* with the second ends of adjacent segments connected together and the first ends of adjacent segments being connected respectively to the first and second bodies. An inner ring connected to the inner segments and an outer ring connected to the outer segments with the inner and outer rings including portions electrically insulated from each other to provide two separate electrical conducting paths. A spiral electrical conducting spring connected to each separate electrical path, one end of which is fixed and the second end limiting rotational movement of the leaf spring.
