I was wondering if you can change the switch status via the input msg.payload true/false.  
My switch is configured to send "led=on" when switched on and "led=off" when switched off.  
Now I'm looking to control the switch status (being on or off) of the switch node input.  
When I send payload true or false to the switch it is not reacting.

What happens if your inject nodes send "led=on" or "led=off" instead of true and false?

According to the built-in help for that node:

> In pass through mode the switch state can be updated by an incoming `msg.payload` with the specified values, that must also match the specified type (number, string, etc). When not in passthrough mode then the icon can either track the state of the output - or the input msg.payload, in order to provide a closed loop feedback.

Then it works. That's not how I expected it to work though.

I don't want it to pass through because then it would create a loop.  
If I change the state to

Then I can't control the switch manually anymore.  
If I change it to

Then it won't reflect the actually state...

Feed the output back to the input, or use it in pass through mode with a Filter node on the output to break the loop.

You don't need to use a Function node, you can use just a Junction node.
