Operate a switch node using a html button

HI,

I have to create a function to operate a switch using a html buttons (ON_switch and OFF_switch) by using a template node and stay in the same url page /switchbtn when click.

flow

The switch node belongs to node-red-dashboard, which means once you add that to the flow, you will automatically have a dashboard at https://<ip>:1880/ui containing this button.
You can send true/false/on/off to the button and it will switch. See example.

So currently you are mixing up 2 things: template and dashboard. Unless I misunderstand what you are trying to do.

To build custom pages I would recommend ui-builder
