Push on off latching circuit using a push button switch | 555 timer projects

A tutorial on how to make a Push on Push off latching circuit using a single momentary Push button switch. An explanation on how the circuit works is also included. This Push on off latching circuit is a variant of T Flip Flop realised using a 555 timer IC.

For circuit diagram plus more Info, visit:
** Adding the article right now. Will update the links once it's done**

Components Required:
* 555 Timer IC
* 1 tactile/push button switch
* Resistors: 270R, 2 x 10K, 100K
* Breadboard
* Power Supply: (5-12)V
* Few Breadboard connectors
Note: For supply voltage of more than 9V, use 1K resistor for LED instead of 270R

Sometimes simple things needs simple explanation, thanks for your time very appreciated😊

Honestly I was about to use an expensive arduino to do a simple pull up button but thank God you made this video! So damn simple and much much cheaper to do for refurbishing a lamp. This does exactly what I needed it to do. Thank you sir!

This circuit is PERFECT for my project. I looked at several different latching circuits made of discrete components, but if you press the button steadily, the circuit self-toggles based on the RC time constant. This circuit lets you hold the button forever without changing states. I didn't have to change any component values, worked first time. PERFECT! The 555 is 50 years old but is still very useful, and has a high current output (200 mA) compared to digital chips. TYVM for sharing this.

This is all I've been searching for. A Simple on/off of one light witha single momentary switch. Thank you!

[martinhorner]

Still works and still one of the simplest and best designs and explainations of the 555 toggle latch on YT.

I've watched a lot of videos on setting up a 555 timer and this is one of the oldest yet most helpful and easy to follow vs any of the newer videos

This is the best explanation for the pin 2 Trigger, and pin 6 threshold, that i never see!!!!
Congratulatios!!!!

This cicuit is called....
Flip Flop type
Toggle!!!

This is such a great turorial, everything is easy to follow and understand. Keep up the good work!

[PeterPerhac]

Nice! Great job explaining how it works, and a simple to follow tutorial. Very well done. Thank you

[voltampscircuits]

One of the clearest explanations I have ever heard and understood!😃

[prihars]

Thanks you man, I was searching this for more than two days but I finally found your video. Hates of to you

[tuhilsd.i.yscience]

Thanks! I've been trying to make something like this, but wasn't able to. So when I finally understood how this works, I was quite impressed with it!

[jgaracci]

Very well done. I used this with a reed switch, it's perfect.

[emmettbrown]

Best lecture I have ever watched. Thank you.

[VariantAEC]

The most informative video about how pushbutton on/off circuits work.
I'm not sure this is how they work in a PC, but this is the closest explanation I can find so I will share this.

[rajeshparab]

Thank you for this excellent tutorial, your made this circuit so simple and easy to understand, that it worked on the very first attempt, keep up this good work and god bless you !!!

[farazahmed]

was stuck on how this circuit works for days.
Thanks a lot

[steve]

Great tutorial. Can you provide a schematic where 2 LEDs go on and off opposite of each other? Thanks.

[realtrickybilly]

Thank you very much. The explanation is excellent and really helpful for learners - I think it is a great plus compared to tutorials that only teach how to assemble the circuit without explanation. Keep up the good work.

[olvincastro]

Excellent explanation I did it using 6 volts and works well
