When the "ON/OFF" button is pressed once, the equipment goes on and stays on. It goes off when the button is pressed again. The circuit is straight forward. It uses a JK CMOS FlipFlop to with its JK terminals tied high to achieve the toggling action. The clock is provided by the push button used for on/off action. The resistor and the capacitor near the on/off switch debounces the contacts.
Note that when the circuit is switched on, the relay may land in a on or off state. It can be brought to the off state by pressing the RESET button.
I have tried the circuit in the attachment using electrolytic capacitor, but it is not working. Pls advice if anyone could help me or if there is any other simpler circuit out there.
Thanks
