A microsystem component with a device deformable under the influence of temperature changes is disclosed. An analog processing circuit generates a monitoring signal based on the terminal voltage. A space defined in the concave cup is configured for combining the lightweight material layer. In one position the latch member prevents the oven door from opening. The ethylene-hexafluoropropylene copolymer comprises 35 to 60% by mole of ethylene structural unit, 25 to 50% by mole of hexafluoropropylene structural unit and 0 to 15% by mole of structural unit derived from a monomer copolymerizable therewith and has a fluorine content of at least 60% by weight and number average molecular weight of 3,000 to 500,000.
