The type of control provided in the device.
-
Mechanical. Mechanical systems are systems in which the control elements are connected to the working elements of the device directly, 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, which changes the current strength in the heater, etc. Such control, which is mainly implemented by a rotary switch, is simple, reliable and at the same time low cost. True, it does not allow the implementation of some functions and is not particularly accurate in adjusting individual parameters (timer settings, heater temperature); however, in the case of these shortcomings often turn out to be 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.
