The type of control provided by the device.
—
Mechanical. Mechanical are systems in which the control elements are directly connected with the working elements of the device, without the "mediation" of electronic circuits. For example, the power button in such models directly closes and opens the power circuit, the rotary knob of the thermostat rotates the rheostat that changes the current in the heater, etc. Such control, which is mainly realized by a rotary switch, is simple, reliable and at the same time low cost. However it does not allow you to realize some functions and is not particularly accurate in adjusting individual parameters (timer settings, heater temperature); however, in the case of these shortcomings are often insignificant. Therefore, most of these devices nowadays use this type of control.

Push-button. Push-button control is based on electronic circuits. Such systems are more accurate than mechanical ones; more capabilities and modes are provided. On the other hand, such control is more complex and more expensive than mechanical control.
—
Touch. A type of
electronic control with touch switches. Compared to push-button models, it provides a high level of comfort in operation, and looks more modern and aesthetically pleasing.
A special device that holds together the halves of a sandwich maker or other similar device (see "Type") and prevents them from opening during operation.
