Node-RED Dashboard - Update switch dynamically

0

I am creating an IOT dashboard to control some electronics in my home. For this, I'm using NodeRED and the Dashboard.

One question I have: My interface has several Switch buttons that already work normally. But I would like to create another switch that updates all the other buttons (something like turn on / off everything - example of the connected in the room). However, I can not get it to work.

Is there any secret to this?
