  • What is the difference between a circuit breaker and a contactor

    The circuit breaker is protective, can extinguish the arc, and has the ability to segment. The contractor uses the coil to control the on-off of the circuit. After the contactor is energized, the normally open is closed, and the long-closed is opened...

  • Troubleshooting Method for High Noise in AC Contactor Operation

    The noise of the AC contactor in operation is very large, which can be dealt with as follows: 1. The power supply voltage is insufficient, and the suction force of the electromagnet is not enough to generate noise. Try to increase the voltage of the...

  • What are the basic structural components of automotive relays

    The relay sets up a bridge of communication between the blocked or isolated circuits in the circuit so that the current flows and the circuit achieve the predetermined function. Basic structural components of automotive relays 1. The shell, also kno...

  • How to choose an electromagnetic relay

    Depending on the application, the electrical power you are using, and the size and functionality of the device, you can choose between different types of electromagnetic relays. You can even buy one that will come with a one-stop learning guide.  To ...

  • How to use a latching relay

    The latching relay is a type of electrical switch. It has input and output terminals and is applicable for circuit control and single or multiple control signals. There are two types of latching relays - magnetic and static. Read on to learn about ea...

  • What are automotive relays

    Automotive Relays are electrical components that switch circuits on and off. They work by using electrical power, a control module, or a computer to switch one or more electrical circuits. A relay can switch multiple circuits of different voltages. R...

  • How does a latching relay works

    A latching relay is a type of electrical switch that has a remanent core that holds the contacts in their operating positions. To release them, they need a pulse of the opposite polarity. A permanent magnet in a latching relay closes the contacts. A ...

  • What are the common uses of electromagnetic relays

    An electromagnetic relay is a type of electronic switch. It functions when a predetermined impedance or reactance is exceeded. This allows it to convert a small electrical current into a larger one. These switches can be found in a variety of shapes ...
