What is WAN

What is WAN

Wide Area Network: Provide data connection for users distributed in a wide area. Devices: Usually use the transmission equipment provided by the service provider. Switching Type: Circuit-switched packet switching

WAN is a data communication network covering a relatively wide geographic area. It usually uses the convenience provided by public carrier companies for transmission.
The WAN technology plays a role in the next three layers of the OSI reference model (that is, the physical layer, data link layer, and network layer).
WAN usually operates in two switching modes, namely circuit switching and packet switching technology.
The circuit mode is based on the principle of circuit switching in the telephone network. When the user requests to send data, the switch connects a physical data transmission path between the calling user and the called user. The characteristics are small delay, "transparent" transmission (that is, the transmission path does not modify or interpret user data), and the throughput of information transmission is large. The disadvantage is that the occupied bandwidth is fixed and the utilization rate of network resources is low.
The grouping mode is a store-and-forward switching method. It divides the information to be transmitted into packets (packets) of a certain length, and stores and forwards them in units of packets. Each packet information carries the identification of the receiving address and the sending address. Before transmitting the packet, a virtual circuit must first be established and then transmitted in sequence. The grouping method uses dynamic multiplexing technology on the line to transmit each group, and the bandwidth can be reused. The disadvantage is that the real-time is not good.

12Mm Key Switches

 

12mm Key Switches including Electric Key Switch, Key Lock Switch, CAM Lock , belongs to power lock.  It can save space and easily operate with the "innovation and convenience"  design concept. The whole series products are widely used in human-machine panel so it can greatly reduces the space of the control panel. Meanwhile,its shape is different from the other switches,for example Metal Switches , Automotive Switches, Push Button Switches.

Production control of 12mm On Off Key Switch: In order to provide competitive price, quality and stable delivery cycle of the whole series of 12mm power lock switches, the company has the world's advanced CNC production machine and a number of fully automated processing equipment and has successfully imported Toyota lean production system.


Electric key switches

It all adopt the One-stop operation and automated production assembly from development and design,mold manufacturing, zinc-aluminum alloy die-casting, plastic injection, stamping, lathe polishing, baking varnish, product assembly, to quality assurance inspection, etc. As a result, we have accept Japan, Europe and the United States hardware construction industry, as well as large European and American companies commissioned to undertake the manufacture of various locks and related hardware parts.

Diversification of 12MM power lock products: The whole series of power lock products have complete functions. In order to improve the safety and confidentiality of customers' using experience, we could offer customers with different keys to achieve the effect that the keys cannot open each other.
