Solenoid switch 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.
What is a Solenoid Switch?
A solenoid switch is an electrical switch that is frequently used in high current circuits, such as starter motor circuits, where a low current switch is employed to activate the circuit. The solenoid switch is designed to turn on a durable switch that connects the vehicle's battery to the motor's starter. Once the ignition key is activated, the solenoid switch connects the drive pinion of the starter. Sintly solenoid switches are renowned for their high performance, reliability, and durability.
In a solenoid switch, the coil is connected to two of the four connector terminals, which can be isolated from the remaining terminals. This configuration allows the coil to operate independently. The terminals for the switched current are significantly heavier than those for the coil.
How it works?
Solenoid switches are wire-wound magnetic coils comprising an open core and a cylindrical plunger with sliding. Once the coil is activated, a magnetic field can be generated within the hollow opening, which then pulls the cylindrical plunger into it. The direction of the switch and the plunger's poles determine the outcome. In this configuration, the plunger can be connected to a set of switch contacts by means of a mechanical link, enabling the execution of high-power switching operations.
Types of Solenoid Switches
Most of these switches include only one switched pole because of the current flow through them. Some switches operate only for a moment, like starter solenoids used in automobiles. When the engine of an automobile is activated, then both the motor’s starter as well as a switch are 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.
How to Wire a Solenoid Switch
Solenoid switches are used primarily for controlling circuits with high current by using a switch with low current.
These devices feature a switch with high current, controlled through a magnetic actuator known as a solenoid. Once a small current is supplied through the solenoid, the core will move to the force switch, which has a high current and is in a closed position. The solenoid size determines the number of terminals, with four terminals included in larger models. Two terminals are used for low-current circuits, while the remaining terminals are used for the high-current circuit of the solenoid. Connecting a solenoid switch involves a number of steps, as outlined below:
Please connect the terminals of the high-current switch to the solenoid switch and then observe the position of the two terminals as detailed in the supplied documentation.
Please cut two pieces of black wire and connect one end of the initial black wire to the negative terminal of the battery. Similarly, connect the second end of the wire to one of the high-current terminals of the switch.
The remaining black wire should be connected to another high-current terminal of the switch.
The next step is to attach the remaining end of the wire to the DC motor's negative terminal.
One end of the red wire should be cut and attached to the positive terminal of the motor, while the other end should be attached to the positive terminal of the battery. This will create a high-current circuit.
Please cut two pieces of black wire and connect one end of the primary wire to the initial low-current terminal over the switch. The remaining end should be attached to one of the terminals of the 6V switch, with the remaining terminal connected to the negative terminal of the 6V battery.
The Solenoid Switch in Automobiles
The role of the solenoid switch in automobiles is as follows:
When energised, solenoids carry a current which creates a magnetic field. The magnetic field produced by the solenoid switch provides a high-force, high-current source of power for activating devices used in electrical applications and vehicles, including automotive and industrial applications.
The solenoid switch is used to trigger a durable switch that unites the vehicle's battery to the starter motor.
Once the ignition key is in the starting position, the switch connects the drive pinion of the starter.
Applications
The main applications for solenoid switches include:
The solenoid switch is utilised to regulate high-power circuits through the utilisation of compact electrical control signals, thereby activating the switch.
Furthermore, it enables a high-power switching device to be situated remotely. These switches are typically utilised in automotive engine starting systems. This is an overview of the solenoid switch. These switches are manufactured with the finest materials and the highest quality components. The main applications of these switches are in automobiles and industrial processes.
