12V relays belong to a category of relay products, which also have certain requirements for the operating environment. For those who have purchase consideration in this regard, you can refer to the basic knowledge of learning the professional section to determine a trustworthy 12V relay, and you can also learn and analyze in depth during the later operation and processing. So today's popular knowledge is about the working principle of 12V relay and the content with reference value in power calculation. Interested friends can learn from the actual situation.
Electromagnetic relays are generally composed of iron cores, coils, armatures, contact reeds, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow in the coil, resulting in an electromagnetic effect, and the armature will overcome the pulling force of the return spring and attract to the iron core under the action of electromagnetic attraction, thereby driving the armature. The moving contact and the static contact (normally open contact) are pulled together. When the coil is powered off, the electromagnetic suction also disappears, and the armature will return to the original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) are released. In this way, the suction and release are achieved, so as to achieve the purpose of conducting and cutting off in the circuit. For the "normally open and normally closed" contacts of the relay, it can be distinguished as follows: the static contacts that are in the open state when the relay coil is not energized are called "normally open contacts"; the static contacts that are in the connected state are called "normally open contacts". It is a "normally closed contact".
