Dry battery electric contact

The utility model discloses a dry battery quantity electric contact, which comprises a shell, a movable probe capable of moving up and down along a certain range is arranged in the shell, a supporting seat is arranged on the shell, a microswitch is fixedly connected with the supporting seat, the microswitch is provided with a signal line interface and a conductive metal sheet, the bottom end of the movable probe is a detection end, and the bottom end of the movable probe is a contact end. The movable probe moves upwards to extrude the conductive metal sheet so that the test circuit can be conducted, and the movable probe makes contact with the microswitch through pressing so that the test circuit can be conducted and the test is triggered to start for data acquisition at the same time. The conditions of missing detection, data signal transmission interruption and the like caused by asynchronization of the contact time of the positive and negative electrode test rods of the dry battery and the test starting ti
