-16- ELECTRICAL CIRCUIT TESTER Abstract of the Disclosure An electrical circuit tester for use in testing pro- truding electrical connectors such as those found in tele- phone terminal blocks, the tester comprising a body made from an insulating material, the body having a plurality of circuit testing assemblies, each assembly including a chamber, each chamber including a chamber extension exten- ding to the exterior of the body and capable of receiving the electrical connectors. Positioned within each chamber is a piston having a piston rod extending therefrom, the piston rod extending into the chamber extension. The cham- ber includes a piston retaining wall having an aperture through which the piston rod moves. When the piston rod is in its fully extended state, there is room in the cham- ber extension to receive the electrical connector. Posi- tioned within the chamber is a conductive grommet and a re- silient conductive spring which contacts the grommet and functions to urge the piston and piston rod to the fully extended position. The chamber includes an aperture which allows for the insertion of a wire and connection of the wire to the grommet. The wire is run from the grommet to the exterior of the tester, and may eventually be connec- ted to an electronic apparatus for testing the circuits in the telephone terminal blocks.
