The negative pressure switch can be used to detect whether the sucker sucks something.

Yes The negative pressure switch can be used to detect whether the sucker sucks something, because the negative pressure detection technology is adopted in the design of the negative pressure switch, which can detect the tightness between the sucker and the sucked object and whether something is sucked, and even if a small object is sucked, it can effectively avoid leakage. At the same time, through the negative pressure detection technology, the adsorption force of the sucker can be automatically adjusted to adapt to the sucked objects of different sizes, and the use efficiency of the sucker is improved. So the negative pressure switch can be used to detect whether the sucker sucks something.
