METHOD OF RECOVERY OF ELECTRIC LOW-VOLTAGE APPARATUS CONTRACTS

摘要

The invention relates to techniques reduction of low voltage electric apparatus and may be used advantageously in the recovery height of the contacts more than 1 mm high current switching devices. The purpose of the invention - stabilization geometrical dimensions of contacts, the contacts increase durability and strength of braze joint. For this method the reduction of low-voltage electrical apparatus contacts comprising mounting contacts on the contact carrier by soldering spot welding machines are used have become unusable contacts on a substrate of ferrous metal with a work surface roughness of not more than 300 microns. ff
