Catalysis of the transfer of potassium ions (K+) from one side of a membrane to the other. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: K+(in) + H+(out) = K+(out) + H+(in). Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: solute(out) + H+(in) = solute(in) + H+(out). Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: cation A(out) + cation B(in) = cation A(in) + cation B(out). Catalysis of the transfer of hydrogen ions from one side of a membrane to the other. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: monovalent cation(out) + H+(in) = monovalent cation(in) + H+(out). Catalysis of the active transport of a potassium ion across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.
