Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, the present invention is a kind of volume mimic-disconnecting switch little, easy to use, comprise pick-up unit 1, processor 2, display 3 and input key 4, DC power supply circuit 5, hand jumper ring circuit 6, hand conjunction coil circuit 7 and anti-jump coil circuit 8 is included in processor 2, pick-up unit 1 is connected with processor 2, and processor 2 is connected with display 3, and processor 2 is connected with input key 4, processor 2 is single-chip microcomputer, and display 3 is light-emitting diode display.
As shown in Figure 2,3, 4, a kind of mimic-disconnecting switch method of testing, comprises the steps:
S1: program powers on;
S2: initialization;
S3: read dial-up;
