I've been caught on this before I think but want to check.
What exactly does that mean?
This is the code this time:
```auto
[{"id":"d3c31e8d.90ed7","type":"ui_button","z":"caed37a2.771dc","name":"","group":"6ab22327.a2f71c","order":18,"width":"2","height":"1","passthru":true,"label":"button","tooltip":"","color":"","bgcolor":"","icon":"","payload":"3","payloadType":"num","topic":"","x":330,"y":380,"wires":[["6741e2f8.7766f4"]]},{"id":"f2826600.de653","type":"inject","z":"caed37a2.771dc","name":"","topic":"","payload":"8","payloadType":"num","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":160,"y":380,"wires":[["d3c31e8d.90ed7"]]},{"id":"6741e2f8.7766f4","type":"debug","z":"caed37a2.771dc","name":"","active":true,"tosidebar":true,"console":false,"tostatus":true,"complete":"payload","targetType":"msg","x":510,"y":380,"wires":[]},{"id":"6ab22327.a2f71c","type":"ui_group","z":"","name":"HOME","tab":"273de47d.2d2bac","order":1,"disp":true,"width":3,"collapse":false},{"id":"273de47d.2d2bac","type":"ui_tab","z":"","name":"TEST","icon":"dashboard","order":4,"disabled":false,"hidden":false}]
```
I `inject` a value of `8` and go through the `button`.
But I get a `3` in the `debug` node.
So the `emulate a button click` means **forget what is sent in, you are getting the output as though the button was pressed**.
Not just pass the message through.
On the `switch` node (dashboard) it says this:
> Pass though `msg` if payload matches new state
How does this compare to the button's _pass through_?
> **If payload matches new state**
So sorry for the brain failure.
But I just want to check.

Emulate button click means exactly that, it is like pressing the button.
In your button node, you say 'send 3 when the button is pushed' so that is what is send whether you press the button or send a msg to the button which acts like you pressed the button - 3 gets sent out in msg payload,

I know it was (probably) a stupid question, it just caught me out - maybe again.
