Description

A buffered contact power transmission device

technical field

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

Background technique

The word switch is interpreted as on and off. It also refers to an electronic component that can open a circuit, interrupt current, or cause it to flow to other circuits. The most common switches are human-operated electromechanical devices that have one or more electrical contacts. The "closed" of the contact means that the electronic contact is turned on, allowing current to flow; the "open" of the switch means that the electronic contact is not conducting to form an open circuit, which does not allow current to flow; it needs to be used in the automated production process. Special switching devices, such as contact power transmission devices, however, traditional contact power transmission devices are rigid in structure and have a single function, especially without buffering effect, and the contact power transmission effect is not ideal.
