Is it possible to make toggle button with relays?

Serhioromano · Jun 8, 2017

For example I have 222V AC and as many relays as I need. Can I make togle button? One push turn it on and another push turn it of?

Add a power supply.

I do not need this kind of relay, I know they exists. I want to simulate the same behavior using really logic with simple relays for demonstration of principle behind.

Check this:

You can click the "open in editor" button and simulate it.

This will work with relays. (Original by Archie.)

Can I use AC here?

this will not work simply by wiring relays. Because you have one I0 inverted. To implement this I need physical NC contact on the button. I need 2 contacts one NO and one NC and also I cannot press them simultaneously.

So to implement this scheme I need Stop-tart buttons block.

Yes it will. Use your push button to drive a 4 pole relay. Then you have both normally open and normally closed contacts. Or get a push button with both NO and NC contacts.

AC or DC makes no difference if you use the right coil voltage

Getting a pushbutton with multiple contact blocks isn't a problem. However, here's Saffa's solution using three relays:

Here is a Diagram of an older piece of equipment that used relay logic to toggle some lights on and off.

This one has a button that has both NO and NC contacts. I was looking for only one contact button.

But anyway it is very nice one. Thank you.

This one works perfectly.
