Comparison Electrolux EHAW-7510D vs Electrolux EHAW-7525D

The type of control provided in the device.

Note that mechanical and electronic devices can use the same elements - buttons, rotary knobs, sliders — and, as a result, almost do not differ from each other in appearance. The difference lies in the fact that the mechanical control directly affects the working part of the device (for example, when the knob is turned, the resistance of the rheostat that regulates the power changes), and the electronic control sends a signal to the control circuit, which accordingly changes the parameters of the device. The advantages of mechanical ones are simplicity, reliability and low cost. However, it allows you to adjust only basic functions, and the accuracy of the adjustments is low. In turn, with electronic control, various additional features can be provided and individual operation parameters can be very precisely adjusted. But such control is more complicated and expensive. Electronic control can also be performed in the form of touch controls, which gives the device elegance and elevates it to a more advanced level.
