Abstract

PURPOSE: To enable identification of closed switch by providing an oscillation circuit which oscillates at frequency different with closure of each sensor switch for safety operation and by emitting the alarm sound by means of the speaker.
CONSTITUTION: When the sensor switch SW1 is closed, the oscillation circuit consisting of 2 NAND gages N, condenser C and resistance r1 oscillates at frequency by the time constant circuit consisting of resistance r1 and condenser C, and the output is amplified by the low freqeuncy amplifier AL of the automotive radio AR, outputting alarm sound from the speaker SP. Since the alarm sound of a tone corresponding to sensor switches SW1WSWn is emitted, closed sensor switch can be immediately identified in accordance with the tone of alarm sound. In addition, the use of automotive radio for this system has the advantage of simplified circuit and less cost.
