How Do 12V Car Solenoids Work?
The Solenoid as Actuator Solenoids may act under your control as a driver or passenger, or the control of the vehicle’s computer-Engine Control Unit (ECU). You may order a solenoid to lock or unlock the electric door locks by pushing a button, for example. In the same way, the computer may order solenoids to regulate temperature, vacuum flow, pressure and other tasks for best engine performance. How a Solenoid Operates Every time you push the button on your electric door lock, electrical energy travels to a solenoid. This electrical current then travels through a small winding in very close proximity to a metal core inside the solenoid. The magnetic filed created by the current on the winding causes the core to move and act on the lock mechanism to lock or unlock the door. Different Types of Solenoids Some electro-mechanical solenoids are equipped with a return spring. This helps the core or plunger inside the solenoid to return to its original position once electrical current is shut
