Abstract

1331831 Retractive switches J L LAMBERSON 10 Feb 1971 4813/71 Heading H1N [Also in Division G5] In a question and answer teaching device, depression of a correct answer area of a printed sheet or card against resilient means causes a conductive patch on the rear of the printed sheet to complete an electric circuit including a lamp and a buzzer. As shown (Fig. 4) a printed sheet 4 overlies an elastomeric foam plastic pad 12 having apertures 13 therein exposing first and second interspaced grid conductors 8 and 9. The sheet 4 has characters, symbols and pictures printed thereon in position corresponding to the apertures 13. Selected areas of the back of the sheet 4 have conductive patches 6 coated or stuck thereto in register with the corresponding openings 13. In use, a pupil is instructed to indicate a specified character, &c. If he selects a character corresponding to a patch 6, then depression of the sheet 4 in that area will bridge conductors 8 and 9 and complete the circuit of a lamp and a buzzer 14. The whole device is arranged in a casing 1, the sheets 4 being replaceable. A socket for taking a plug from a telegraph key is connected to the buzzer and lamp for Morse code practice and a jack for taking a plug from an electric counter or tape recorder is provided so that the buzzer may be rendered inoperative and results recorded instead.
