Abstract
Abstract An electrical indicating device having an animal appearance with indicator lights, incorporated as a part of the features of the animal, to be energized to indicate selection of a right answer from among a number of possible answers. A casing is formed of two portions which cooperate to define a chamber. The outer configuration of the casing provides an animal appearance, with the indicator lights included as features of the animal. A mounting member fastened within the casing mounts circuitry including a probe that extends out of the casing. The probe includes an inner pin and a surrounding tube separated by an insulator. When the probe is touched to an electrically conductive area, the pin and tube are interconnected to complete the circuitry energizing the indicator lights.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
191 words
An electrical indicating device comprising: a casing member having a first portion and a second portion, said first and second portions cooperating to define a substantially enclosed chamber, said casing member configured to provide an owl configuration; a printed circuit board within said chamber and fastened to one of said portions; a pair of light emitting diodes mounted within said chamber and visible through one of said portions to form the eyes of the owl; an electrically conductive elongated cylindrical tube member fixedly mounted on said printed circuit board and extending through said casing member; an electrically conductive elongated cylindrical pin member positioned within said tube member; an electrically insulating elongated cylindrical sleeve member surrounding said pin member and within said tube member to insulate said pin member from said tube member; spring means biasing said pin member outwardly from said tube member; and a solid state amplifier circuit mounted on said printed circuit board and electrically connected to said light emitting diodes, to said sleeve member and to said pin member and responsive to electrical interconnection of said sleeve member and said pin member to energize said light emitting diodes.
