This requires conducting or insulation resistance to toggle switch and implements test, to ensure button before photoelectricity, electronic product installation
Switch quality meets the requirement of product.
Toggle switch carries out conducting at present or megger test process is mostly to be manually operated.Specific testing procedure is as follows:
Step 1: first test point of selection, is connected to the first of device under test for conducting resistance test equipment and fixture manually
A test point；
Step 2: selecting second test point of corresponding first test point, conducting resistance test equipment and fixture are connected manually
It is connected to second test point of device under test；
Step 3: operation conducting resistance test equipment is tested；
Step 4: first test point of selection, is connected to the first of device under test for megger test equipment and fixture manually
A test point；
Step 5: selecting second test point of corresponding first test point, megger test equipment and fixture are connected manually
It is connected to second test point of device under test；
Step 6: operation megger test equipment is tested.
The test for completing a connection relationship, the toggle switch thrown for hilted broadsword list will carry out 2 above-mentioned steps, and double
Knife or three knife toggle switch will then carry out 4 times, 6 times, and even more multiple operation easily causes tester tired.And it is every
Secondary operation causes the consistency of test and stability low due to test fixture change in location.High temperature performance test is carried out in switch
When, when chamber temperature reaches set temperature, switch heat preservation regular hour, when test, need to open chamber door, successively take out switch
It is tested, the temperature decline for testing environment is very fast, is not able to satisfy and carries out under the conditions of set temperature to the performance of switch
Test, authenticity and the validity of test result cannot be guaranteed.However, being continuously increased in digitlization, integrated product type
Under the background of update, since the electronic product performance that the requirements such as product energy consumption, performance, volume cause is improved to toggle switch etc.
The requirement of electric elements performance is also higher and higher, no matter traditional test method is all for testing efficiency or measuring accuracy
Be no longer satisfied existing production needs.

It is made of MPU and switch boards, the master control system received is instructed the control circuit being sent in switch boards, to control
Data selector processed opens the toggle switch of corresponding position, and circuit controls corresponding electromagnetic relay according to instruction and beats on or off
It is disconnected, thus test point and test equipment are connected；
Low resistance test macro:
To generate electric current I constant all the way by the port of switch, while acquiring the voltage U of switch two sides, foundation；
The contact resistance value of switch is calculated, test data is then uploaded to the end PC and shows and stores；
Insulation measurement instrument:
Test is completed by the instruction that PC machine end provides starting test and terminates test, and is uploaded to test data by serial ports
The end PC shows and stores；
Test fixture plate:
It is the testboard for testing toggle switch, positions toggle switch position by 16 way switch stations.
This device replaces the method manually tested, and improves the special screening efficiency of toggle switch, reduces tester
Labor intensity, and improve the precision of test result.Collect sampling, test, addressing, amendment, self calibration in one since system utilizes
Body digitizing technique can not only realize fast and accurately digital test, not need to carry out biggish improvement to existing system,
It can cooperate different test equipments by the quadratic programming to control software, be developed on the basis of existing control circuit
More test functions have wide applied to other electronic components, the group parts even testing process of system level
Application space.
