A temperature controlled switch has a temperature controlled switching mechanism and a housing for containing the switching mechanism. The housing comprises an upper part having a first external connection terminal and a lower part having a second external connection terminal, wherein a first contact surface is provided on the inner side of the upper part and connected to the first external connection terminal, and a second contact surface is provided in the inside of the lower part and connected to the second external connection terminal, wherein, the switching mechanism comprises a snap-action disc, on which at least one outer contact region and at least one inner contact region are provided. A movable contact part is held on the inner contact region and interacts with the first contact surface. The at least one outer contact region is connected at least in sections permanently to the second contact surface. The snap-action disc lifts off the movable contact part from the first contact surface depending on the temperature of the switching mechanism. The snap-action disc has at least one compensation section between the at least one or each outer contact region and the at least one or each inner contact region.
