Abstract
PURPOSE:To obtain a change-over circuit that controls plural circuits through the on-off of a switch, by using the 1st counter which delivers an output when the on- time of the switch is longer than the set time plus the 2nd counter which works with the output of the 1st counter and the switch input. CONSTITUTION:When the switch SW1 is turned on, the signal of SW1 is supplied to the counter 2 and gate 3. The counter 2 delivers pulses with a certain interval of time through a built-in clock oscillator, counts the on-time of SW1 with the clock signal and then delivers an output with every fixed time after a set time and when the on-time of SW1 is longer than the set time to supply the output to the gate 3. An AND is secured at the gate 3 between the on-signal of SW1 and the output of counter 2, and this output is supplied to the monomulti 4. The monomulti 4 works by the output pulse of counter 2 and corresponding to the on-time of SW1, and then operates the counter 5 with its output. The counter 5 cuts off the relay 6a with the output of monomulti 4 to actuate the relay 6b. Then the realy 6b is cut off with the next pulse to actuate the realy 6c. In such way, the relays are changed over sequentially.
