SW3 Solenoid Starter Switch
A starter solenoid is the part of an automobile which switches a large electric current to the starter motor in response to a small control current, and which in turn sets the engine in motion.
Its function is thus identical to that of a transistor, but using an electromagnetic solenoid rather than semiconductor to perform the switching.
In many vehicles the solenoid also engages the starter pinion with the ring gear of the engine.
It also called “Starter Solenoid Relay Switch” or “Solenoid Relay Switch”.
1.An idle starter solenoid can receive a large electric current from the car battery
and a small electric current from the ignition switch.
When the igenition switch is truned on, a small electric current is sent through the starter solenoid .
This cause the starter solenoid to close a pair of heavy contacts,
thus relaying a large electric current through the starter motor,
whcih in turn sets the engine in motion.

Features
If a starter solenoid receives insufficient power from the battery,
it will fail to start the motor, and may produce a rapid clicking sound.
The lack of power can be caused by a low battery, by corroded or loose connections in the battery cable,
or by a damaged positive (red) cable from the battery.
Any of these problems will result in some, but not enough,
power being sent to the solenoid, which means that the solenoid will only begin to push the engagement gear,
making the metallic click sound.
