Abstract

A circuit tester which allows the testing of electrical outlets, telephone circuits and light bulb sockets. The circuit tester is cylindrical with two circuit probes. The first probe is a conventional two-prong electrical plug and the second is a conventional male light bulb connector. A standard telephone jack socket is provided on the side of the cylinder.

Claims

1. An apparatus for testing circuits comprising:

a) a housing;

b) a telephone line testing circuit mounted in the housing;

c) an outlet probe mounted on the housing;

d) a light bulb probe mounted on the housing; and

e) a circuit in communication with the outlet probe and the light bulb probe affixed within the housing.

2. The apparatus of claim 1 in which the circuit comprises:

a) a visual indicator;

b) an audible indicator; and

c) a first switch in communication with the probes and the indicators for selecting an indicator mode.

3. The apparatus of claim 2 further comprising

d) a second switch in communication with the probes for selecting a probe mode.

4. The apparatus of claim 3 further comprising a safety cap removably affixed to the housing in which the circuit further comprises at least one safety interrupt switch positioned on the housing such that the safety cap engages the safety interrupt switch when the cap is affixed to the housing.

5. The apparatus of claim 1 further comprising a safety cap removably affixed to the housing.

6. The apparatus of claim 1 further comprising at least one safety interrupt switch positioned on the housing such that the safety cap engages the safety interrupt switch when the cap is affixed to the housing.
