Abstract
A transfer element (8) is provided in a thermal switch (1) with a housing (2), power supply lines (4) and contacts (5) and (7), with a contact spring (6) and a thermostatic bimetal plate (3). The transfer element is moved up by the snap action of the thermostatic bimetal plate and in so doing takes with it the contact spring (6), opening the contacts. In order to adapt this transfer element (8) in its length precisely to the desired nominal length, a heating into the deformation range of the material forming the transfer element (8) takes place, with a subsequent deformation of the upper edge region. This makes it possible in a simple way to produce the exact nominal length of the transfer element (8).
