However in order to solve this problem, using various switching techniques and electronic circuits, we can make a combination of Solid State Relay(s) connected to an electronic module, so that we can make ...
The main motive of Solid State Relay(s) was to replace the use of conventional Mechanical Relay(s) for various switching applications. ...
The best example is the electromechanical relay
which exerts magnetic force on the contacts of the
switch when the coil placed near to it becomes
electrically energized. ...
