There is no limit in timed circuits, there is no stopping, this type of circuits can be made with all kinds of transistors or different components, but since I like 555 circuits more, I designed them using 555 again.

With this circuit, you can set the time interval yourself on the pot and activate the relay at the desired time interval and make it work...

You can connect an external cable to the place where BTN is written on the PCB, connect a button or switch type switches, put the circuit in a more suitable plastic box, and use the circuit in a separate place and the button in a separate place...

Since I designed the circuit for myself, I wanted to leave out the button area and share it in case it might be useful to you.

I haven't tried the circuit, but it's still worth checking...!
