• critical points of nondifferentiable functionals
• discrete eigenvalue problem
• discontinuous nonlinearities

Using a three critical points theorem for nondifferentiable functionals, we investigate a class of second order difference equation with discontinuous nonlinearities. A new multiplicity result is obtained.
