Electronics Press ON Hold OFF latching circuits (2 Solutions
Fig. 1 Circuit schematic of a latching push button ON/OFF power switch for a microcontroller based product, allowing the microcontroller to turn itself OFF. In this circuit, a momentary button press turns ON power to the microcontroller, and latches it ON. A second press can initiate shut down, or the microcontroller can turn itself OFF.
Simple Soft Latch Switch using PushButton ElectronicsLab
A Discover Circuits visitor needed a latch circuit which could operate using a power supply voltage ranging from 3v to 24v. He wanted to use a tiny pushbutton switch to turn on and off power to a load. However, he wanted a 2 second delay between the switch activation and the state change of the output.

Push on Push off Switch Circuit Latching Circuit Diagram YouTube
The circuit below performs this logic function with just a few parts and can operate from DC supplies between +3v to about 15v. It uses two inverters within a 74C14 or a CD4069 hex inverter package. Each press of the button toggles between the two on/off logic states. The logic output is connected to a PMV65XP p-channel FET from Philips.

Latching Power Switch Circuit (Auto Power Off Circuit) Random Nerd
A flip-flop or latch is a circuit that has two stable states and can be used to store state information. The circuit can be made to change state by applying a signal (in this case, by pushing a button). Here, I will show you three different ways to make latching circuits: Using 555 Timer IC Using Transistors Two Switches

1 Try connecting a load because the leakage current from the p channel mosfet will turn on the n channel mosfet which in turn will activate the p channel mosfet and reproduce the unwanted effect you witness.
Push button switch(Latching) interfacing with PIC Microcontroller with
Press-ON Hold-OFF MOSFET circuit controls low-voltage electronic devices Sometimes you need a high side latching power switch that will work well with low voltage, such as that produced by batteries. Two AAA or AA battery cells in series produce, depending on the state of charge and battery chemistry, between 1.8 and 3.5 volts.
