Tips: What causes the contact resistance of the isolating switch to increase?

The reason for the increase in contact resistance is: the repulsive force of the contact between the blade and the knife tip is very large, and the knife edge is not tightly closed, which causes surface oxidation and increases the contact resistance. Secondly, the disconnecting switch will cause arcing during the pulling and closing process, burn the contacts, and increase the contact resistance.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
