Abstract

PURPOSE:To increase the reliability of a switch (SW) signal transmitting circuit, by transmitting the SW signal when a coincidence is obtained between the output of an SW effective time setting circuit that starts its operation at the 1st switching operation of an SW and the output of a counting circuit of the switching frequency. CONSTITUTION:When an SW4 is operated, a time setting circuit 6 delivers an SW effective time (3) at the fall time point t1 of the SW4 and by the output given from an SW filter 5. At the same time, the terminal output A of a counter circuit 7 is set at 1. Then the output A of the circuit 7 is set at 0 with the 2nd switching operation of the SW4 and at the fall time point t2. Thus the terminal output B is set at 1, and the output (2) of the circuit 7 is set at 1 since the output B is kept at 1. As the effective time of the circuit 6 is set at a value from the time point t1 to t4, an AND8 is secured between signals (2) and (3) to transmit the SW signal (4) to an SW signal receiving circuit 2. A display circuit 9 shows the SW effective time by a lamp and meanwhile gives three times the switching action to the SW4.
