Because the contact pair will break instantaneously when it is subjected to vibration, impact and collision, the electrical continuity of the contact pair during vibration, impact and collision should be considered in order to ensure high reliability in use. The main basis for judging the instantaneous fault of contact is duration and voltage drop. Both of them are indispensable. The prescribed instantaneous break time is generally 1_ S, 10_ S, 100_ S, 1_ MS and 10_ Ms. If the voltage drop at both ends of the closed contact exceeds 50% of the power supply electromotive force during this time, then the fault of closed contact can be judged. .
