Hi,  
My project is simple for now:  
I have 3 physical buttons which I connected to my relay board. Each button is connected to a separate relay and what node can I use to prevent simultaneous pressing of two or three buttons at the same time. I am looking the whole web to do so but there are all topics with one button or multiple presses on a single button.  
I want to make the whole sequences for each buttons with relays but for know I must know how to push only one button at the same time.  
I think the function node will be helpful for that but I don't know javascript language.

I will be very grateful for your help

I'm guessing the physical buttons "lock" when pressed.  
So you press it, and it stays in a condition.  
You press it again and the condition toggles.

I don't know if that will be easy.

You may need to go to press buttons (momentary press, non-locking).

Then you will have to make a bit of _code_.  
Each button sets a `topic` for its message.

All 3 messages are sent into a _node_ (`function`) and a lot of work happens in there.

Sorry, it is 21:11 local time and I woke up this morning at 05:45 local.  
(Gotta love insomnia.) ☹

Here is a sample of how you could do it with the `trigger` node

Thank you Trying\_to\_learn and zenofmud.  
I have Raspberry Pi4 and I want to use GPIO 3 physical push button to steer some sequences with relays. Each sequence will take 120 seconds. Now when I push button it doesn't "lock" when pressed is momentary.  
So with trigger node I must prevent other buttons to activate other sequences for 120 seconds

@zenofmud has a good starting point.

I am new to NR 3.x

I don't want to step on his work, but I would do it slightly different.  
Rather than the 4'th `inject`: a `delay` node set to `120` seconds and it sends the `reset` message.

Something like this:

```auto

I am sorry but I am beginner with node-red so it will be best to swap Reset node with delay node?

That is something you left out in your original post BUT it is easy enough to handle, just edit the `trigger` node and change it like this:

 ![Screen Shot 2022-10-28 at 6.28.54 AM](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/c/3c2ee2e0b51df624d07f198266f4e893393a626e.png)

and you can get rid of the 'Reset' button

[EDIT] changed the `then send` to `nothing`

(Sorry again)

But neither of the flows allow toggling of the output.

But that could be handled after the `switch` node with a `function` node that toggles.

@aquapark_lodz do you want all 3 buttons **disabled** for 120 seconds though?

So you press a button and can't press another for 120 seconds?

Or just don't want more than one pressed at any one time?

Here's a very quick modification of the flow created by @zenofmud  
Once a button has been clicked, the delay is triggered so further clicks are ignored until 'msg.reset'.

So I correct my node with sugestions but nothing happened.

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/2/12c31d7f91112592d2d76fcb145065596cdfeb00.png)

I setup trigger for 5 seconds to test it but with trigger node on the startup it's only delay time for 5 seconds from push button to working rest of the code.

My goal is as follow:  
we have 3 physical buttons:  
Yellow button - to start some sequence with relays - working time 120 seconds  
Blue button - to start some sequence with relays - working time 120 seconds  
Red button - to start some sequence with relays - working time 120 seconds

When I push for example blue button and start some sequence for 120 seconds I want to prevent to push other buttons to start yellow button and red button sequence when blue button sequence is working at the moment. when the sequence is over I can again choice which of 3 sequences I can use

please export your flow and attach it to a response and I'll take a look.

So it does - just imported your flow.

The _problem_ with the flow as is, that the relay/s will never be turned off.

You need to do just a bit more between the `switch` node and the `GPIO-OUT` node.

Basically you need a `function` node to receive the message and toggle what is sent to the GPIO pin.

One on each of the outputs.

(code in the `function` node as best I can make it just now)

```auto
let x = context.get("state") || 0;

x = (x + 1)%2;
context.set("state",x);

msg.payload = x;
return msg;

```

Great minds think alike.

Change the `5` seconds to `120` of course.

Thank you for such support I am very grateful for your time.  
So I attach photo of my desk to test

 ![20221028_124357](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/0/90738af587cd520a02823ca7487b97c0958ad0d4.jpeg)

You can see that I want to make sequences for each buttons: for example when I push blue button the sequence starts: 10 seconds to open relay number 1, 2, and then relay 1, 2 close and relay number 5, 7 open for 15 seconds, and then relay number 10, 11 open for specific time. I have to think also to add rgb light to this and sound. So it will be the whole sequence for one button during 120 seconds.

my code is below
