从目前的接线图上看，这样接应该不是用于通断作用，如果需要通断，应该是另一组触点作用。接下来说说我的看法。把常开触点和常闭触点接在一起引出一根线，应该是要把这根线上的信号波形抓出来，线圈通电，触点由常闭位置分开。信号会经历一段空白期，然后再另一个位置闭合，开关过程完成。示波器之类的仪器记录波形，然后，线圈断电，由闭合位置断开，信号同样会经历一段空白期，示波器也会记录下来。然后目的就是分析波形，得出开通关断的时延，开通关断的时间，开通关断瞬间触点的震动带来的波形震荡，从而得出继电器的触点机械特性与电气特性。

From the current wiring diagram, this connection should not be used for on-off function, if it needs to be on-off, it should be another set of contact function. Next, let's talk about my opinion. Connect the normally open contact and the normally closed contact together to lead out a line. It should be to grasp the signal waveform of this line, the coil is energized, and the contact is separated from the normally closed position. The signal will go through a blank period, and then another position will be closed, and the switching process will be completed. Oscilloscopes and other instruments record waveforms. Then, the coil is powered off and disconnected from the closed position. The signal will also go through a blank period, and the oscilloscopes will record it. Then the purpose is to analyze the waveform, get the opening and closing delay, the opening and closing time, and the waveform vibration caused by the contact vibration at the moment of opening and closing, so as to get the mechanical and electrical characteristics of the relay contact.
