Abstract

The invention relates to a cooking hob with a cooking hob plane (10) for placing a cooking utensil (18) and a switch (16) arranged beneath the cooking hob plane (10) for activating at least one function of the cooking hob. According to the invention, the switch can be actuated by magnetic force. In order to make use of the magnetic force applied to or produced by the cooking utensil (18), it is proposed that the switch (16) is configured to magnetically interact with a cooking utensil (18) arranged on the cooking hob plane (10).
