1. A hand-held totally insulated, non-contacting electrical probe comprising:

  • a probe tip formed entirely of an electrically nonconductive material;

    sensor means mounted entirely within the probe tip for sensing the presence of electrical energy radiated from an electrically conductive member when the probe tip is positioned adjacent the member;

    indicator means mounted in the probe tip for indicating the presence of the electrical energy;

    integrated circuit means supported within the probe tip for receiving a signal from the sensor means and transmitting the signal to the indicating means;

    casing means formed entirely of an electrically nonconductive material, said casing means holding a power source for operating the sensor means, the integrated circuit means and the indicating means; and

    bonding means for bonding the probe tip to the casing means.
