The indicator lights produced by GQEM have the following advantages
Due to the use of LED as the light source, it has the advantages of low power consumption and energy saving compared with traditional light sources (such as incandescent lamps and tungsten halogen lamps). Save energy by 85%.
The life of LED is as high as 50,000 hours, which is 25 times that of incandescent lamps, which greatly reduces the maintenance cost of signal lights.
The LED light source itself can emit the monochromatic light required by the signal, and the lens does not need to add color, so there will be no defects caused by the color fading of the lens. The company adopts LED light wavelength and light color according to national traffic standards.
Traditional light sources (such as incandescent lamps and halogen lamps) need to be equipped with reflectors in order to obtain a better light distribution, while LED traffic lights use direct light, which does not have the above situation, so the brightness and range are significantly improved.
Ultra-thin structure design, beautiful appearance, fine workmanship.
Easy to assemble, disassemble and maintain.
Use PC shell or stainless steel shell, high strength and long life.
To sum up, LED signal indicators of different materials have their own advantages and disadvantages, and appropriate products should be selected according to the needs of actual application scenarios.
Circuit breakers, contactors, intermediate relays, thermal relays, buttons, indicator lights, universal transfer switches and travel switches are the eight most common components in electrical control circuits. The editor introduces the principles and applications of common electrical components with pictures and texts. Get a handle on how these components work in normal times by understanding their role in the electrical circuit.
1. Circuit breaker
Low-voltage circuit breakers are also called automatic air switches, which can be switched manually, and can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. Automatically cut off the circuit.

2. Contactor
The contactor is composed of two parts, the electromagnetic mechanism and the contact system. The common coil voltages of the contactor are AC220V, AC380V and DC220V. The electromagnetic mechanism of the contactor is composed of a coil, a moving iron core (armature) and a static iron core; the contactor contact system is composed of two parts, the main contact and the auxiliary contact, the main contact is used to switch the main circuit, and the auxiliary contact is used to control in the circuit.

Waterproof push button switches, as the name suggests, are switches that can be operated with wet hands. In some humid environments, it can be used with confidence because it has good sealing performance. The highest IP rating of the waterproof switch is IP68. The waterproof button switch has a reasonable design, long service life, high temperature resistance, and current shock resistance, which can meet your specific use needs.
Precautions
The specific application of these waterproof switches is restricted by many factors, such as the installation method and the installation direction of the product, the pressure difference of the airflow acting on the product, the strength of the fluid rebound and the working voltage. We also need to prevent the intrusion of corrosive gases or the intrusion of substances.
The waterproof metal switch cooperates with the circuit breaker to perform switch operations according to the needs of the system operation mode, and change the system operation wiring mode.
