China Ningbo Anyo Import & Export Co., Ltd. certification
Time is flying away, remember the first time we met in Ningbo in the year of 2005. I'm so happy with you and your team. Thanks for your support and let's look forward to the next years together.

—— Mr. Halit vergili

From partner to friend, you always give me surprise for your goods and service. We appreciate it so much. By the way, the pickled fish sauce is so nice. I'm self-confident of my cooking skills again. Don't forgot hot pot date next time.

Automobile relay 4120 7pin SPDT 40A for car electrical control, 26*21*21mm

 

Description:

 

A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and most have double throw (changeover) switch contacts.

 

What do you do when you want to switch on the light ?

you push on the switch….a little piece of metal connects the circutis….taddaaa light works, Relays are exactly the same….a switch, a little piece of metal that connects a circuit except that this switch is not triggered by your fingers, it is triggered by an electro-magnet. the electromagnet is a copper coil wounded around an iron piece, when this coil receives a small electric current, it turns into a magnet, this magnet moves the switch mechanically and press the switch on or off for you.

The main usage of relays is control….exactly like normal switches, you control a device ( say a big motor) to ON or OFF state.

 

Single Pole Double Throw (SPDT):

Such relay consists of a pair of coil pins, a common pin, a normally open (NO) pin and a normally closed (NC) pin. When the relay is not activated, the common pin is in contact with the NC pin and when it is activated, the common pin will break away from contact with the NC pin and subsequently makes contact with the NO pin. Also, when the relay is deactivated (from activated state), the common pin will conversely break away from contact with the NO pin and return back in contact with the NC pin.

 

Applications:

Relays are used in electronics to switch a smaller current which in turn will control larger current. They prevent the user to have direct contact to the main device being controlled that might be holding high voltage. These devices are comparable to a remote c ontrol which is used to make a big electronic equipment work.
