通常，测试接点电阻的目的是确定接触点氧化或其它表面薄膜积累是否增加了被测器件的电阻。

Often, the purpose of the contact resistance test is to determine whether contact oxidation or other surface film buildup has increased the resistance of the device under test.

电触头亦称触点或接点，是电器开关、仪器仪表等的接触元件，担负着通断电流的任务。

Electrical contact also called contact or contact junction, is the contact component of electric switch, instruments and meters and so on, which takes on the task of current on or off.
