Latching device having a cardioid-shaped latching stud for a push-button switch

摘要

In this latching device having a cardioid stud and cardioid-shaped guide surface, the latching pin of the latching element slides on the base of the latching groove, the base having a multiplicity of surface elements, including a rising, wedge-shaped surface, arranged adjacent to the starting surface of the latching pin in such a manner that the rising, wedge-shaped or oblique surface element is at a predetermined distance from the cardioid stud, so that smooth rising of this surface element is achieved and the lower end of this rising surface element merges in a flush manner onto the outer end of the surface element in which the latching pin ends its path.
