A method for producing a temperature-sensitive electric switch, comprising a snap-action element, preferably a snap-action disc, made of a thermostatic bimetal, and a spring element as a movable contact section, a fixed contact section against which the movable contact section can be moved for closing the contact, a pressure pin as an operative connection between the snap-action element and the spring element, a pin guide in which the pressure pin can be guided along a pin guide axis, a housing which has a clear internal diameter, and a cover, wherein the method comprises the following steps: - sliding of the housing, which forms a movable unit with the pin guide, at least partly over a plastic part of a switching bridge unit along a mounting axis, wherein the switching bridge unit consists of a switching bridge and the plastic part, and the switching bridge consists of a first part and a second part, wherein further the first part forms a first terminal section and the fixed contact section and the second part a second terminal section and a connecting section to which the spring element is fastened, and wherein the first part and the second part are embedded in the plastic part, and are connected to each other and are fixed in position with respect to each other by the plastic part; - insertion of the pressure pin into the pin guide and sliding the pressure pin in the direction of the spring element until the pressure pin is seated with one end on the spring element; - displacing the housing in a direction parallel to the mounting axis and measuring the length of a free end section of the pressure pin with which the pressure pin protrudes beyond an opening of the pin guide, which faces away from the spring element, in a direction facing away from the spring element; - fixing of the housing in a fastening position on the plastic part, wherein the length of the free end section corresponds to a predetermined value in the fastening position, wherein at least one mounting pin is positioned with a first end on the plastic part, and wherein the housing, which comprises at least one recess for the at least one mounting pin, is pushed with the at least one recess over a second end of the at least one mounting pin in the direction of the plastic part. - sliding of the housing, which forms a movable unit with the pin guide, at least partly over a plastic part of a switching bridge unit along a mounting axis, wherein the switching bridge unit consists of a switching bridge and the plastic part, and the switching bridge consists of a first part and a second part, wherein further the first part forms a first terminal section and the fixed contact section and the second part a second terminal section and a connecting section to which the spring element is fastened, and wherein the first part and the second part are embedded in the plastic part, and are connected to each other and are fixed in position with respect to each other by the plastic part; - insertion of the pressure pin into the pin guide and sliding the pressure pin in the direction of the spring element until the pressure pin is seated with one end on the spring element; - displacing the housing in a direction parallel to the mounting axis and measuring the length of a free end section of the pressure pin with which the pressure pin protrudes beyond an opening of the pin guide, which faces away from the spring element, in a direction facing away from the spring element; - fixing of the housing in a fastening position on the plastic part, wherein the length of the free end section corresponds to a predetermined value in the fastening position, wherein at least one mounting pin is positioned with a first end on the plastic part, and wherein the housing, which comprises at least one recess for the at least one mounting pin, is pushed with the at least one recess over a second end of the at least one mounting pin in the direction of the plastic part.
