What is the difference between self-locking push button switch and self-resetting switch switch?

Self-locking button switch is a common self-locking button switch. Self-locking switch is a common button switch.

When the switch button is pressed for the first time, the switch is turned on and held, that is, self-locking, when the switch button is pressed for the second time, the switch is turned off, and the switch button pops up at the same time.

The self-locking switch means that when the switch is pressed, the self-locking function will not automatically pop up. When you press it, the button will not pop up when you release your hand. It is in a locked state. You need to press it again to unlock it and completely pop up. It is called a self-locking switch.

This type of switch was used in early TV sets and monitors that were completely powered off.

The difference between the self-locking switch with light and the ordinary self-locking switch is only that: the lighted switch makes full use of the space in its keys to place a small indicator bulb or LED,

One end is connected to the neutral line, and the other end is generally connected in parallel with the normally open contact of the switch through a voltage-reducing resistor. When the switch is closed, the device also provides power for the indicator light while it is running.

Ethernet Switch

Test items
The performance indicators are tested using a dedicated Ethernet test instrument, and the test results of these performance indicators can also evaluate whether the LAN system meets the acceptance requirements. From GBT21671-2008 "Ethernet-based LAN System Acceptance Evaluation Specification", it can be understood that LAN can also judge performance by measuring performance indicators such as network throughput, transmission delay, and packet loss rate. The Ethernet tester is a rugged test platform suitable for field use. It has a complete Ethernet test function, dual optical ports and dual electrical ports, Ethernet service interface module, HST-3000 supports multiple data stream tests. Including 10/100/1000M Ethernet link traffic generation and troubleshooting, it can test electrical and optical port links up to 1Gbit/s. Due to the limitation of various conditions in the acceptance inspection, point-to-point or routing network testing can be supported for routine testing of switches.
The problem
The overall characteristics of modern test instruments are high reliability, high performance and high applicability. Therefore, the gap between domestic test products and foreign products is reflected in this aspect. Although some domestic testing equipment is close to the international advanced level in certain performance indicators, there are generally few products with comprehensive equipment performance indicators that meet international standards. In addition, most of the domestic test instruments are common specifications, which cannot meet the test work in some special environments. Low-level automated testing is also a common problem. [3]
Switch test technology
Nowadays, switches put forward new requirements on the performance of switches based on application requirements. There have been new developments in comprehensive network services, security, and intelligence. Protocol testing is a basic switch testing technology. The network protocol is to improve the efficiency of testing and the effectiveness of communication to ensure the rules of communication. In the era of increasing network communication, network protocols are also indispensable. The basic requirements of network protocols are correct functions, good interoperability and superior performance. The initial prototype of protocol testing is software testing, and the main categories are black box testing, white box testing and gray box testing.
