1、 Features

The vacuum auxiliary switch is just emerging in China. Because the contact adopts the vacuum tongue reed tube, it has the advantages of reliable on-off no leakage of arc compared with the traditional contact insert pressing type auxiliary switch. The permanent magnet is installed in the rotating disc of the actuator, the contact is close to off the magnetic field, the disc does need to rub with the contact mechanically, the rotation is light flexible, there is no stuck condition, the vacuum auxiliary switch does need to be overhauled, which is a leap of auxiliary switch manufacturing technology.

2、 Purpose

Zkf6 vacuum auxiliary switch is suitable for closing, opening, interlocking signal circuit control of high-voltage switch operating mechanism. It can also be used as conversion combination switch on high-voltage switch cabinet.
