Description

Contact type power transmission device with buffer

Technical Field

The invention relates to the technical field of contact power transmission, in particular to a contact power transmission device with a buffer.

Background

The words switch are to be interpreted as open and closed. It also refers to an electronic component that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common switches are electromechanical devices operated by a person, in which there are one or several electrical contacts. The "closed" of the contact means that the electronic contact is conductive and allows current to flow, and the "open" of the switch means that the electronic contact is non-conductive and forms an open circuit and does not allow current to flow; in the automatic production process, a special switching device such as a contact power transmission device is required, but the traditional contact power transmission device has a rigid structure and a single function, particularly has no buffering effect, and has an unsatisfactory contact power transmission effect.
