What is a Solenoid Switch : Working & Its Applications

Switch Solenoid is used in high power circuits for switching purposes by using a small electrical control signal. This switch mainly uses decision making as well as extensive logic circuits to perform on economical microchips & tiny electronic parts. It also allows high power switching apparatus to be restricted to a remote area. These switches are normally used in automobiles to start the engine systems. This article discusses an overview of what is a solenoid switch and its working.

Definition: An electrical switch that is frequently used where a high current circuit namely a starter motor circuit is brought into action with the help of a low current switch is called a solenoid switch. This switch turns ON a durable switch to connect the battery of a vehicle to the motor’s starter. Once the ignition key is activated then a Metal Case Solenoid switch connects the drive pinion of starter. The main features of solenoid switches are high performance, reliability, and durability.

On a Plastic Case Solenoid switch, there are four connector terminals are there where the coil uses two and can be most frequently isolated from all the remaining terminals. So that it keeps the coil totally independent. Generally, the terminals of the switched current are significantly heavier compared with the terminals of the coil.Most of these switches include only one switched pole because of the current flow through them. Some switches operate only for a moment like a starter Proportional Solenoids used in automobiles. When the engine of an automobile is activated, then both the motor’s starter, as well as a switch, is totally isolated from the electrical system. Some of the automotive systems include the moving plunger for sliding the starter pinion with the starter shaft. So that it connects the flywheel and also gives power to the starter motor.

These devices have a switch with high current, controlled through a magnetic actuator known as a solenoid. Once small current supplies through the solenoid, then the core of this will move to force switch which has high current to the closed location. Based on the solenoid size, it includes four terminals. From that, two terminals are used for low current circuits whereas the remaining terminals are used for the high current circuit of the Proportional Solenoid Coil. To connect a solenoid switch, there are different steps involved like the following.

Solenoid Switch in Automobile

The role of solenoid switch in automobiles includes the following.

• Proportional Solenoid With Sensors carry a current that, when energized, creates a magnetic field. This magnetic field produces a high force and current source of power for activating devices used in electrical applications and vehicles, such as automotive and industrialThus, this is all about an overview of the Other Solenoids switch. These switches are made-up with the help of the best rating and huge quality raw materials. The applications of these switches mainly involve in automobiles as well as industrial purposes.
