The working principle is as follows: before use, the first electrode group electrodes 311 are electrically connected to the wire W1.
In use, the elastic insulator 2 is placed close to the object (not shown in the drawings, usually the second electrode set 32, which may also be a conductor electrically connected to the wire W1) until the first electrode set 311 contacts the object.
