Latching Power Switch Circuit (Auto Power Off Circuit) Random Nerd

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.

Momentary latching 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.

AC 380V 10A ON OFF Latching Machine Drill Press Switch Push Button L7W3

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.

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.

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

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.

Simple Latching Circuit using 555 timer

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.

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

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.

Circuit ON/OFF LATCH CIRCUIT WITH 2 SECOND DELAY

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.
