How to read the state of ui-switch in node red

I am in project of one company so i am testing my flow of project with node red

Thast why i want only that person can access the door

So what is your plan to handle that situation? I didn't see that in your design document.

Can you also explain why they might use the RFID reader and then press the switch to close the door? Will it remain open until they leave and use the reader and flip the switch to close? What if they walk out and don't do that? Will the door remain open so anyone could walk in?
