AUTOMOTIVE BRAKE SYSTEM VACUUM SWITCH STRUCTURE

摘要

The present invention relates to a vacuum switch structure for an automotive brake device, allowing various electrodes (terminals) such as a grounding electrode or the like included in a vacuum switch to conveniently and rapidly be fixed to provide more rapid assembly as well as greater rigidity, thereby improving production efficiency. In an automotive vacuum switch (S) including: a diaphragm (300), which includes a housing (100) having a flow path for air and a cover (200) coupled to the housing (100) to allow pneumatic pressure to be applied in the interior thereof; an operation electrode (310); a ground electrode (400); an input terminal (500); and an output terminal (600), the vacuum switch structure is integrally formed through injection on a grounding piece (700) made of synthetic resin to allow the grounding electrode (400), the input terminal (500), and the output terminal (600) to easily and simultaneously be separated or assembled to a coupling groove (210) of the cover (200).
