Metal Push Button Switch
Yeswitch Metal Push Button Switches, also call Push Button Switch , is the most popular switches around the Switch Industry. This Illuminated Push Button Switch can be found on valuable machine and public ticket dispenser applications, along with other industrial type applications that require vandal resistance in a public setting
Our Push Button Switches are available in 19mm, 22mm and 25mm installation size . We have Momentary Push Button Switch and self -lock metal switches, which mechanical life could respectively reach 1,000,000 and 500,000 cycles. This metal switches are normally made of stainless, brass with mirror chrome plated, brass with nickel plated, AL alloy and other Industrial materials.
On the items of button type, We also offer flat, high and round with LED light for our customers to choose from. Meanwhile, this metal switches could equip with LED light, which have Various color . What worthy to be mentioned is that we could offer double color LED light, like red&green,red&and blue, red& and yellow,etc. In addition,the light type could be without LED,ring(fixed),sport, ring(moveable).
The advantage of this switches is that its water resistance to IP67 ratings, and have TUV, European and American environmental protection RoHS and lead-free environmental protection certification . Furthermost, its operation temperature could range from -20-85, which indicates that this metal switch could work in the very hash environment with .
The terminals of our Metal Switches could be silver,gold cover silver and gold,which have very excellent electrical conductivity could greatly support all kinds of equipment and facility.

Fibre Channel technology is detailed, what is the difference between single mode and multi mode?
Fibre Channel is a high-speed, reliable network storage technology designed to facilitate the transfer of large data files between storage systems, servers, and client nodes over long distances. Operating at speeds ranging from 2Gbps to 16Gbps, it was initially developed for supercomputers but has since become a standard in enterprise storage area networks (SANs). Despite its name, Fibre Channel can also run over twisted-pair copper cables, making it more flexible than its name suggests.
The Fibre Channel Protocol (FCP) functions similarly to TCP, enabling the transmission of SCSI commands over the network. It bridges the gap between traditional I/O interfaces and modern networking technologies, offering both performance and scalability. Unlike open networks that are unpredictable, Fibre Channel operates in a structured, closed environment where devices are known in advance, ensuring stability and controlled communication.
One of the key goals of Fibre Channel is to provide a high-speed, scalable interface that supports long-distance data transfer. This is achieved through fiber switches, which allow for the connection of thousands of devices across a single network fabric. The ability to support multiple upper-layer protocols makes Fibre Channel adaptable to various applications while maintaining compatibility with existing systems.
Compared to older technologies like SCSI or ESCON, Fibre Channel offers significant improvements in speed, distance, and manageability. Fiber optic cables are easier to install and maintain than copper wires, and they are less susceptible to electromagnetic interference and crosstalk. Additionally, Fibre Channel enables non-disruptive installation and service, allowing components to be added or removed without shutting down the entire system.
In a Fibre Channel environment, devices such as servers, storage arrays, and tape drives are referred to as "nodes." Each node has one or more ports—physical interfaces used to communicate with other nodes. These ports can be of different types, including N_Ports, F_Ports, NL_Ports, FL_Ports, E_Ports, and G_Ports, each serving a specific role within the network.
Fibre Channel uses two main types of optical fibers: single-mode and multi-mode. Single-mode fibers have a smaller core diameter (9-10 microns) and use long-wavelength light for long-distance transmission, typically up to 10 kilometers. Multi-mode fibers, on the other hand, have larger cores (50 or 62.5 microns) and are more cost-effective, but they suffer from modal dispersion, limiting their effective range.
The network structure in Fibre Channel is often referred to as a "fabric," which is a switching or routing infrastructure that directs data based on destination addresses. Fibre Channel supports three primary topologies: end-to-end, switched fabric, and arbitrated loop, along with hybrid configurations that combine the benefits of each.
End-to-end topology allows direct communication between two nodes, while switched fabric enables connections between many devices via a central switch. Arbitrated loop offers a balance between simplicity and scalability by connecting multiple nodes in a looped configuration. Hybrid topologies combine elements of these structures to optimize performance and cost.
Overall, Fibre Channel remains a critical technology in enterprise storage environments due to its reliability, speed, and flexibility, making it an essential component in modern data centers.
