Don't know the specs of those switches but for example:
240v / 1A = 3.7V / 65A
It's the watts that matter... You only need to convert accordingly the specs from one voltage to the other. Now if the spec listed for the switch are something like 120V / 0.5A then at 3.7 you only would have 16A which might be marginal.
