Abstract

Indicating test apparatus for testing any one of a selected number of electrical components and comprising an indicating test unit having a plurality of electrically operable indicator means to provide an indication of proper circuit operation. The indicator means are adapted for connection with the selected component by means of interchangeable programmed connector means including a disconnect peculiar to the component being tested and a connector for removably connecting the disconnect means with the indicator means. Interchangeable overlays corresponding to the interchangeable programmed connectors and having indicia thereon peculiar to the selected component may be provided. Means may also be provided to vary the test unit'"'"''"'"'s output voltage which is measured by a voltmeter.

Claims

1. Apparatus for testing A selected one of a number of different kinds of electromechanical components each of which is adapted for removable connection to disconnect terminal means peculiar thereto and normally forming part of an electrical operating circuit, said apparatus comprising means forming an electrical test circuit independent of said operating circuit and having a plurality of indicating means;

substitute disconnect terminal means for removable connection to said selected one of said components only when the latter is removed from the first mentioned disconnect terminal means and is electrically isolated from said operating circuit, said substitute disconnect terminal means corresponding to said first mentioned disconnect terminal means and being peculiar to said selected one of said components;

a preprogrammed connector means selected for use with said substitute disconnect terminal means, connected to said substitute disconnect terminal means and removably connected to said test circuit for connecting the former in circuit with a selected number of said indicating means of said test circuit as determined by said preprogrammed connector;

interpreter means having indicia thereon peculiar to said selected one of said components and removably located adjacent said selected number of said indicating means;

said test circuit comprising a direct current output power circuit connected to said plurality of indicator means, and adapted to be connected in circuit with said removable connector means to complete the circuit with the selected number of indicators;

direct current supply input circuit means adapted for connecting to a direct current source for providing a direct current voltage to said direct current output power circuit;

alternating current power supply input circuit means adapted for connection to a source of alternating current and having an output circuit means for providing a variable direct current output to said direct current output power circuit; and

selector switch means for operatively connecting said output power circuit means in circuit with a selected one of said direct current input circuit or said alternating current power supply input circuit while simultaneously precluding connection with the other.

2. Apparatus as set forth in claim 1 further including an accessory unit for testing a circuit breaker and including a source of direct current and variable resistance means adapted for connection in circuit with openable and closable switch contacts of said circuit breaker, said test circuit including meter means connected to said accessory unit for monitoring the current flow through said circuit breaker when its contacts are closed.

3. Apparatus as set forth in claim 1 wherein said output power circuit includes momentary contact switch connected in circuit with one of said indicator means for permitting the output voltage to be adjusted prior to completing the circuit to said selected one of said components being tested.
