It is a switch that is operated electrically, it is also a control object (actuator) that will turn off or on when the conditions are met. When the electricity, magnetism, sound, light or heat output reaches a certain value, the output will change by leaps and bounds. The voltage of the automobile power supply is mostly 12V, so the coil voltage is mostly 12V.The automobile relay consists of 3 parts： ● The magnetic circuit system: Coil, Iron core, Yoke, Hinged armature ●The contact system: Fixed contact, Moving contact, Contact base ●The restoring mechanism: Restoring reed or Tension spring. Make & Break Relay It is also known as SPST (Single-Pole, Single-Throw). There are 4 pins (or terminals) on the body with one high current circuit and contact. The contact is opened or closed depending on whether the relay is at rest or energized.☑Avoid direct sunlight and maintain normal temperature, humidity, and pressure as below: 1. ● Temperature: 10 ℃ ~ 35 ℃ 2.● Humidity: 5 ~ 85% RH 3. ● Air pressure: 86 ~ 106kpa. ☑ Regularly check the products in stock and try to avoid the relay storage time being too long. ☑The relay shall be stored and installed in a clean environment. Please use a dust cover or plastic encapsulated relay in the environment with dust pollution.Changeover Relay It is also known as SPDT (Single-pole, Double-throw). There are 5 pins (or terminals) on the body, there are two contacts connected to a common terminal. The relays have two circuits, one is closed when the relay is at rest, and the other is closed when the relay is energized.● If the contact is closed when the relay is at rest, the relay is called Normally Closed (NC). 2. ● If the contact opens when the relay is stationary, the relay is called Normally Open (NO). These relays are the more common type.
