We identify within topological particle theory a broken SU(2) "electrospin" symmetry and enumerate a related collection of exact and approximate conservation laws. One component of electrospin, equal to $Q\ensuremath{-}\frac{1}{2}(B\ensuremath{-}L)$, is always conserved. The connection of electrospin with strong and weak isospin is discussed.
