Fitting a casing of a switching device

摘要

A casing (11) of a thermostat (12), which is to be fixed to the rim (17) of a reception container (16) for a heating device, is substantially inserted in a recess (23) of the rim (17). The recess (23) is open to the outer edge of the rim (17) and has two lateral boundaries (24). In the fitted state the casing (11) forms a mechanical connection between the lateral boundaries (24) and closes the transmission of forces in the course of the rim (17) and in particular clamps together the rim in the circumferential direction. The fastening of the casing (11) and the bracing takes place by means of at least partly bent round and/or bend roundable fastening tongues (25) and/or clamping tongues (27), preferably emanating from the lateral boundaries (24). The invention inter alia leads to a positionally reliable positioning of the thermostat (12) on the reception container (16).
