[0002] Connectors are a type of component that electronic engineers often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in a circuit, so that current can flow and the circuit can achieve the intended function. Therefore, the application range of connectors is also very wide. Among them, when connectors are used in electrical products with switches, they are generally contacted by pressing the plastic parts to touch the spring switch. In order to reduce false touches, poor contact, etc., the contact method is generally point contact. Overall, it is easy to accelerate product failure. In addition, traditional switches are limited by their structural form and usually can only be processed by reflow soldering, which has a higher cost and a relatively small current transmission.
