Abstract
A switch head is disclosed that can be attached to a temperature sensor having elongated expansion elements with different thermal expansion coefficients. The switch head further includes a device for measuring the displacement of the expansion elements relative to each other. Attachment means are provided for attaching at least one additional switch head. At least one opening for receiving a transfer member to transfer the relative displacement of the expansion elements to the at least one additional switch head is provided.
Claims18
A temperature limiter, comprising:
- a temperature sensor for measuring a temperature below a cooking area, said temperature sensor including elongated expansion elements having different thermal expansion coefficients;
- at least one switch head which includes a device for detecting a relative movement between the expansion elements;
- and
- an additional module constructed to initiate a heating of the cooking area or monitor a state of the cooking area, said additional module having a base component provided with a bore, wherein the additional module is placed over the temperature sensor or the at least one switch head by way of the bore, wherein the additional module comprises a resistor secured to the base component for monitoring a temperature of the cooking area.
