1. Micromechanical shunt exhibiting hysteresis, comprising:

  • (a) an insulating substrate having a planar top surface;

    (b) a first contact terminal on said planar top surface;

    (c) a second contact terminal on said planar top surface;

    (d) a cantilever beam having a free end and a fixed end which is attached to said first contact terminal, said free end being suprajacent said second contact terminal;

    (e) means for establishing an electrostatic charge attraction between said cantilever beam and said second contact terminal; and

    (f) a resistance layer intermediate said cantilever beam and said second contact terminal;

    whereby said free end of said cantilever beam may be deflected toward said second contact terminal by establishing an electrostatic charge between said first and second contact terminals.
