Abstract. We present a unified description of gravity and electromagnetism in
the framework of a $Z_2$ noncommutative differential calculus.
It can be considered as a ``discrete version" of
Kaluza-Klein theory, where the fifth continuous dimension is replaced by two
discrete points. We derive an action which coincides with the
dimensionally reduced one of the ordinary Kaluza-Klein theory.
