What is infinite switches?

Infinite switches are electrical devices used in stovetops or ranges to control the heat of heating elements such as stove burners. These switches are called "infinite" because they provide a continuous range of power adjustment rather than offering pre-set temperature settings like conventional thermostats. The user can adjust the heat intensity at any level from low to high based on the required cooking temperature. The infinite switches typically consist of a potentiometer and a switch that connects to the heating element. When the dial is turned, the potentiometer adjusts the output voltage to regulate the heat intensity of the heating element. Infinite switches are commonly used in commercial kitchens and most home stovetops around the world.
