A grounding method adapted for a power supply is provided, and which includes: providing a circuit body corresponding to the power supply, where the circuit body has an input part and an output part; disposing the circuit body in a shielding layer; and making at least one of the input part and the output part to be coupled with the shielding layer through at least one capacitor. At least one edge region of the stack does not include electrodes. The first and second link connection points are accessible via a link opening in the terminal unit body and a removable link comprising a link conductor and a link handle is removably insertable into the link opening. The swivel snap can be used for enhancing a variety of fishing mechanisms including the shank of jigs and the spindle of lures and other apparatus attached to fishing lines. Preferably, the extrudate is thermoplastic, polyester, elastomeric material and at least one additive may be present. The second pulse is configured such that the second ejecting element is applied to the pressure generator when the meniscus is located at a second position that is farther from the pressure chamber than the first position after the second expansion element is applied to the pressure generator.
