Contactors are generally used in the line to realize the opening and breaking of contacts, because when used in frequent start-stop occasions, it will cause the coil and contacts to be damaged. If the coil is damaged, in fact, there is no need to repair, the main reason is that the maintenance is difficult and costly, and the main contact damage is the same, and it is not recommended to repair. So when the auxiliary contact of the contactor is damaged, should we repair it?

Auxiliary contact, is not the same, such as interlocking circuit, auxiliary contact bad will affect the entire circuit, if because the auxiliary contact is bad, and replace the entire contactor, it is inevitable to cause waste, disassemble the contactor maintenance is also more troublesome, although the auxiliary contact is not a precision part, but as part of the contactor as a whole, if disassembled and repaired, affecting the integrity of the contactor is inevitable.

If the auxiliary contact is repaired, it is more trouble-saving and time-saving, whether it is NO or NC.

ContactorsThere are two commonly used forms, one is the card slot type, this is the most common, if this is broken, it is easier to solve, directly with the same plug-in as destroying the contact, can be solved. Another form of contactor, no slot, now not too widely used, its auxiliary contact is fixed with screws on the contactor body, this if broken, directly removed, replace the same model of accessories on it, convenient and fast.

This method is more commonly used, in addition to solving the problem of auxiliary contact damage, you can also use this method in the case of more functions that need to be controlled and converted, and its effect is also acceptable.
