It allows the operator to vary the connected heating circuit according to the selected control position. This switch is useful for applications where consistent heat adjustment is required during cooking or warming cycles. They can be used when an existing switch becomes worn, damaged, or fails to respond properly to control changes. Its switching function provides a direct connection between the control knob and the heating circuit for manual heat regulation.
