the working principle is as follows: taking two switching value test units as an example, the two switching value test units are respectively a first switching value test unit and a second switching value test unit; testing whether the switching values of the two switching value testing units are conducted or not;
(1) Taking the switching value connected with the first switching value test unit as a test object:
Turning on the switch 5 of the first switching test unit, both the first LED2 and the second LED3 of the first switching test unit are on; at this time, since the switch 5 of the second switching value testing unit is not turned on, the first LED2 of the second switching value testing unit is not lighted (i.e., the first LED2 is used to indicate whether the corresponding switch 5 is turned on);
If the second LED3 of the second switching value test unit is on, it indicates that the switching value connected to the first switching value test unit is turned on; if the second LED3 of the second switching value test unit is not lit, the switching value connected to the first switching value test unit and the switching value connected to the second switching value test unit are not turned on.
