PURPOSE:To enable time control for a plurality of load control patterns, by outputting the output signal at the start and stop end of the time limit output from one time set means and providing the pattern switch driving circuit controlling two sets of pattern switches. CONSTITUTION:The output waveform of a timer circuit 1 is inverted at a transistor TRQ1, integrated 19, differentiated 23, and TRQ3 is on with this output signal to drive the relay Ry2 and to obtain the signal for start end A of the time limit output. Then, the output waveform of the inverter 20 is further inverted at an inverter 21, differentiated 22, and TRQ2 is on with the output signal to drive the relay Ry1, and the contact X of the pattern switch 4 is on to obtain the signal for the stop end B of oscillation output. |
