Abstract

A shock proof electrical probe comprises a probe tip, a casing for housing batteries, and a cap, each formed entirely of an electrically nonconductive plastic material. To establish an energizing circuit for the probe, the interior of the casing is provided with an elongated electrically conductive strip which extends longitudinally from contact with a circuit board in the probe tip, to an opposite open end of the casing, where the strip is mounted to the casing so as to bendable into electrical contact with an adjacent battery pole, and bendable in opposite direction to permit selective insertion and removal of the batteries from the casing. The probe further includes a steel carrying clip which is entirely encapsulated in electrically nonconductive plastic material. The probe may be of a noncontacting type, which utilizes an antenna for detecting the presence of an AC voltage, or a contacting type for detecting a the presence of a DC voltage. In either instance, when a voltage is present, a light-emitting diode is energized to produce a glow within the probe tip.
