NMOSFET and NPN latching switch Electrical Engineering Stack Exchange
These MOSFET circuits are suitable for use in new products, medical devices, analytical instruments, and any microcontroller based embedded system. Two behaviors are often needed: A Press-ON-Press-OFF toggle switch, in which a short touch of the button latches the circuit ON and another latches it OFF; and, A Press-ON-Hold-OFF toggle switch, in.
Press ON Hold OFF latching circuit Multisim Live
Trying to make the Press ON - Hold OFF latching circuit from Mosaic-Industries work, but clearly I have no idea how to connect the Power source (a 12V battery pack) or the circuit/device to be powered.
Push button switch(Latching) interfacing with PIC Microcontroller with
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.
Soft latching switch no working as intended (assistance appreciated
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 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 Answer Sorted by: 0 Your question is poorly formed. What holds it on and what holds it off? In falstad or the real world? What power levels? ac or DC? What starts it? Forever? Do you want a controllable switch? For the circuit you show, try an analog switch.

So what do you do? Enter the latching power circuit, often referred to as a "soft" switch. [Chris Chimienti] has recently put together a fascinating video which walks the viewer through five.

Three Push ON Push OFF Latching Circuits 3 Steps Instructables
Press ON Hold OFF (Almost) No power draw when OFF since my idea is for it to be battery-powered I would love to read the state of the button with a microcontroller, but the microcontroller can't be used for the latching part, I'm already stretching the MCU thin, and I would need to add an IO expander which I would rather not do at the moment.
Latching Power Switch Circuit (Auto Power Off Circuit) Random Nerd
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.

Momentary latching switch
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.
