I edited your post to so it would display normally instead of looking like shouting)

What have you tried so far? Have you connected a `debug` node (set to display the Complete msg object) to the outpput of the `u-switch` to see what it is returning.

Where do you intend to store the output?

what kind of message? if it is not in msg.payload, then you will need another node (maybe a `change` node) to create the message you want to pass,

So you will need to test the output of the `ui-switch` node. Which of the [core nodes](https://nodered.org/docs/user-guide/nodes) do you think you could use for that purpose?

Debug node for checking the output?

</div>

is that your answer to my question of how you can test the output? If so, have you noticed that the debug node is a dead end node (i.e. it doesn't have an output)

Go back and look at the core nodes again (I provided you a link to them) and try again.

Let me rephrase my query to you.

You have a msg coming from the `ui-switch` node. The msg contains information you need to test to see if it should be sent to the `mqtt-out` node so you have  
`ui-switch ------> ????? -------> mqtt-out`

What do you need to put in the middle (where the ?????? marks are) in order to text the contents of the msg and determine if you should send the msg on?

Sir,i know you want me to know ,but according to what i have done is

Sir ,The half issue is solved but like i will explain in steps:  
Mqtt code  
1: in this code i have switch case for user like case1: if that ui switch is in real triggered (means Open )then publish message (my own mesg) to mqtt out node  
2: similarly for Close ui switch

I'm sorry but I do not understand what you just said.

1 - If you still have an issue export your flow and attach it to a reply.  
2 - Then, please explain in more detail what your current issue is

Note: I will be going out for about 2 hours and will respond when I get back.
