Toasters and waffle irons with mechanical switch

Mechanical

— mechanical systems refer to control systems where the control elements directly interact with the working elements of the device, without the involvement of electronic circuits. For instance, in such models, the power button directly opens or closes the power circuit, and a rotary knob adjusts the current in the heater through a rheostat. This type of control, commonly achieved with rotary switches, is simple, reliable, and cost-effective. However, it may have limitations in implementing certain functions and lacks precision in adjusting specific parameters such as timer settings or heater temperature. Nevertheless, these limitations are often insignificant, and as a result, the majority of devices nowadays use this type of control.
