We consider classes of non-manipulable two-valued social choice functions, i.e., social choice functions with range of cardinality two within a larger set of alternatives. Corresponding to the different classes, the functional forms are described. Further we show that they, and some others from previous literature, can all be unified using a common structure. Such a structure relies on the concept of character function we introduce. This is a function from the domain of the admissible profiles, that notably we do not assume to be universal, to a partially ordered set. The proper choice of the character function, marks the distinction among different classes and permits the description of all social choice functions of a class in simple terms.
