Description

[0002] The reed switch, also known as the tongue reed switch or magnetic reed switch, is a special magnetically sensitive switch. The basic structure of the reed switch is to seal two magnetic reed sheets in a glass tube. Although the two sheets overlap, there is a small gap in the middle. When there is an external magnetic field, the two magnetic reed sheets will contact and then conduct. Once the magnet is pulled away from the switch, the magnetic reed switch will return to its original position. The reed switch is simpler in structure, smaller in size, higher in speed, and longer in service life than a general mechanical switch. Compared with an electronic switch, it has the characteristics of strong resistance to load impact and high working reliability. At present, the glass tube in the reed switch needs to be cut to a fixed length during the production process. In the prior art, it is generally cut manually, which makes the cutting efficiency low.
