Automatic shutoff is developed on irons
Descripción:
To prevent fire or unwanted burns resulting from unattended irons, designers began to put a function in irons that turned it off automatically after a certain period of disuse. This did not prevent scorching, but did greatly reduce the chance of serious harm or injury stemming from an abandoned device.
