Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage switches, and more specifically, to a low-voltage switch with intelligent alarm. Background Art

[0002] Low-voltage switches are roughly divided into three categories: automotive low-voltage protection switches, pressure-controlled low-voltage switches, and low-voltage switchgear for power equipment. They are suitable for the automotive industry, water purifier industry, power industry and other fields. Low-voltage switches have different meanings in different fields. There are roughly automotive low-voltage protection switches, pressure-controlled low-voltage switches, and low-voltage switchgear for power equipment. Most of the current intelligent alarm low-voltage switches use screws to pass through the low-voltage switch to fix it in the position where it needs to be fixed, making the entire fixing process inconvenient, and its overall structure is directly exposed to the outside world, which easily causes a large amount of dust to adhere to its outer surface, causing the dust to affect it.
