This circuit can be used to toggle another circuit on or off by pressing a momentarily on push button.
The 40106 inverting Schmidt trigger and resistor-capacitor network on the left act as a switch debounce circuit to create a positive pulse on the J-K flip flop 4027, which toggles the output on or off. The circuit toggles as soon as the switch is pushed and retains its state when the switch is released.
This can be modified to toggle when the switch is released by swapping the switch and the resistor capacitor network so that the switch pulls up to +V instead causing a negative pulse on the flip-flop.
