Description
Technical field
The present invention relates to a kind of A.C. contactor switch module, the auxiliary contact group of a kind of A.C. contactor.
Background technology
A.C. contactor with fast shut-off ac circuit, and can connect the circuit dress that big electric current controls frequently
Putting, A.C. contactor uses work to control in motor, shop equipment, electric heater, machine-tool and various shop unit etc. widely
Electrical load, and A.C. contactor also has low-voltage release guard effect, is the critical elements in automation control system,
And auxiliary contact group is used to the control circuit of break-make small area analysis, it is achieved the self-locking of catalyst, interlocking, the state transmission of catalyst
Etc. function, and control the circuit while that other needing.But the auxiliary contact group of conventional AC catalyst generally uses contact
The way of contact of formula, contact is applicable to forceful electric power signal identification, but the resistance between contact contact is relatively big, does number of times along with dynamic
Increasing and the passage of time, contact can aoxidize and may be stained with dust, and contact resistance can become big many, for 5V's or 5mA
Weak electric signal identification ability is more weak, is not suitable with weak current equipment facility, however as social development progress, along with the improvement of equipment changes
Entering, industrial computer, a large amount of uses of PLC, it is more extensive that weak electric signal is also applied, and the seizure to weak electric signal also becomes with identifying
Even more important.
Summary of the invention
