Press ON Hold OFF latching circuit Multisim Live
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.

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.

Author Topic: Push-On, Hold-Off Latching Circuit Small Issue (Read 2958 times) 0 Members and 1 Guest are viewing this topic.. I'll attach a way of controlling this with an MCU GPIO pin. The long press Off would be detected by the MCU, but have no other direct effect. And the button could be used for other input while the MCU is on..

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.
Simple Soft Latch Switch using PushButton ElectronicsLab
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.

Online schematic capture lets hobbyists easily share and discuss their designs, while online circuit simulation allows for quick design iteration and accelerated learning about electronics.
Press ON Hold OFF latching circuit Multisim Live
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.
Simple soft power latching circuit for a microcontroller Electrical
It uses one push button to turn on (momentary), turn off (long press) and reset (momentary). If you look throught their website you will find different circuits for different needs but i think this should do it. I have simulated it in spice and it works just fine.
Soft Latching Power Circuits Circuit Cellar
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 Latching Circuit using 555 timer
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.
Press and Hold Latching Circuit Questions Page 1
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
A Press-ON-Hold-OFF action, where a short press turns power to a circuit ON, but a longer button hold is needed to toggle it OFF. The soft power switch circuit designs shown on this page provide both functions. You may also be interested in: ON/OFF switches that limit capacitor in-rush currents, or,
Push on off latching circuit using a push button switch 555 timer
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.
