Glossary

Control

Rotary switch. Control carried out by mechanical elements directly connected to the corresponding components of the device. The traditional, most popular option provides two rotary knobs: a thermostat and an off timer with a clock mechanism (see “Functions”). The main advantages of this type of control are simplicity and low cost. At the same time, the capabilities of the “mechanics”, although modest, are quite sufficient to control all key functions. Among the clear disadvantages compared to electronic control, it is worth noting less accuracy.

- 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. Touch control is found mainly in top models of juicers.

Rotary switch with sensor. Another type of electronic control, where the main control is a rotary switch, which is complemented by touch buttons. The switch itself simplifies the selection of modes, temperature, timer time, and the sens...ors are secondary. However, the control panel itself looks stylish and is not inferior in design to models with touch controls only.
