Time delay light switch maybe, although you would place that next to the door bell so the visitor has to push both. Of course you could wrap a sense wire around the mains cable to trigger a bell when the light is pushed so there's no high voltage in your DIY circuitry.<br />

If you want to make your own project then you can get breadboards with a NE555 timer already mounted on them.

Thanks both. I have placed an order for the relay. I hope it works the way I see it.

I am looking for a switch which, when turned on, automatically switches off after a predetermined time like 1 minute or two minutes. The application is a door light which is turned on when someone rings the doorbell.<br />
<br />
What would such a switch be called.<br />
<br />
Any link would be welcome from which I can purchase it. Ali Express is preferred as it definitely delivers to my country.

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor). These auxiliary devices are intended to be connected to the computer and used in conjunction with it. Examples of external peripherals include mouse, keyboard, printer, monitor, external Zip drive or scanner, while internal peripherals include CD-ROM drive, CD-R drive or internal modem. Today's new devices, such as tablets, smartphones and wearable computing devices are considered peripherals as they can be connected and used on a computer system. The difference, however, is that these devices can run independently of the computer system.
