The push button switch can complete basic control such as start, stop, forward and reverse, shifting and interlocking. It is common for every push button switch to have two pairs of contacts. Each pair of contacts consists of a normally open contact and a normally closed contact. When the button is pressed, the two pairs of contacts operate simultaneously, the normally closed contact opens, and the normally open contact closes.
With the rapid development of high-frequency power conversion technology, various converter topologies have emerged, and integrated large-scale integrated circuits and power component technologies have made it possible to integrate small and medium-sized power devices, thus rapidly promoting the research of key switch systems. The expansion. The push button switch has the advantages of energy saving, reliability, high efficiency, economy and convenient maintenance. It has been gradually adopted by large computers, communication equipment, aerospace, industrial control systems.
The demand for key switch applications is constantly evolving, and the emergence of new technologies will lead to the replacement of many application products, and will open up more updated application areas. The push button switch is a switch that transmits the sensing result to the circuit device in response to the vibration force and causes the circuit to start working. The realization of high-frequency key switch, modularization, digitization and greening will mark the maturity of these technologies and realize the combination of high-efficiency electricity and high-quality electricity.
The push button switch is a functional electronic switch, which is a standard part. When the button is pressed, the switch can be turned on by tapping the switch button. When the hand is released, the switch is disconnected, and the internal structure is a quasi-metal shrapnel. In order to achieve on-off, the push-button switch is widely used in the household power side due to its small contact resistance.
