Abstract

An integrated logic test probe device employs internal electronics in a variety of external switches for choosing the mode of operation of the probe. As several switches are employed and indicator lights are included as well, it is most desirable to configure the probe to be conveniently hand held with a streamlined shape that allows easy left- or right-handed use with a clear view of the point in logic circuitry being probed.

Appearance Design of an Integrated Logic Probe

An integrated logic test probe device employs internal electronics in a variety of external switches for choosing the mode of operation of the probe. As several switches are employed and indicator lights are included as well, it is most desirable to configure the probe to be conveniently hand held with a streamlined shape that allows easy left- or right-handed use with a clear view of the point in logic circuitry being probed.

The design shown in the figure achieves these purposes as follows: The probe has a housing 1 of generally pin-like streamlined shape that tapers toward the probe end to a connector 2 in which is mounted the pin-like probe 3. A variety of switches 4, 5 and 6 for choosing the mode of operation of the circuitry are housed in the probe. Indicator lights or light-emitting diodes (LEDs) 7 and 8 describe the results of tests conducted by the logic probe in response to the selection of functions chosen on the switches. With the switches all located on the top surface of the probe, together with close proximity to the indicator lights, either hand may be utilized to equal effect. The tapering shape provides a clear view of the point in logic circuitry being probed and the placement of the lettering for the switches allows easy reading from either a left handed or right-handed point of view.
