Device for detecting a liquid level, especially the water level in washing machines or dishwashers

摘要

A large-surface, continuously elastic diaphragm held on the circumference in the pressure cell forms, in conjunction with an inherently rigid switching member connected firmly to the diaphragm over the broad base, a diaphragm arrangement having an inner zone inherently rigid over a large surface and an annularly elastic edge zone; the restoring spring acting counter to the measuring pressure engages centrally on the switching member in the region of the plane formed by the fastening base of the diaphragm. <IMAGE>
