When the hand is released, the switch is not only turned off, but its internal structure is achieved by the force of metal springs. A light touch switch is used by lightly pressing the switch button to turn the switch on. When the hand is released, the switch can be turned off. Its internal structure is achieved by the force of the metal spring to spring. Find the parts at the beginning of the schematic parts library SW, which includes packaging instructions and 3D styles. Key switches are the fourth generation switch products developed with the requirements of electronic technology development. The earliest volumes were 12mm * 12mm and 8mm * 8mm, and now they are 6mm * 6mm. There are three product structures: vertical, horizontal and horizontal with ground end, and now there are two types of combination (3M, 4M, SM, 6M, SM) and Potentiometer key switch combination, which meet the requirements of various domestic electronic products. There are three installation dimensions available: 6.5mm * 4.5mm, 5.5mm * 4mm, and 6mm * 4mm. 4.5mm * 4.5mm small key switch and chip type key switch, which are suitable for surface assembly.
