When designing the first thing you learn is **safety first**. Having a power button on a device generating heat which could be forgotten (as the well known irons) and in some cases lead to a dangerous fire is something we want to avoid. Having a button to push is an easely forgotten task as opposed to pulling the cord from a jack.

This is the reason for not having a power button on non-exclusive heat generating devices. But, there are differences. Exclusive hardware having electronics for safety do have a power button, since it saves the user from error. As in this case:

>This sandwich toaster is designed for people who seek high quality and durable home appliances. Thanks to power button there is no need for pluging cable to the socket every time we want to use this device,
and built-in a timer makes it much easier to use. While using you do not have to check the state of the thing we toast – you only have to set amount time you want (shown by shining diods), after which the sandwich toaster turns itself off and sygnalizes that with a sound.

>Straight handle and special hinge facilitates compressing thicker sandwiches and steel latch will never break. Heating plates are interchangable so the device is much more functional and it’s easier to keep it clean.
