You have to know and understand that everything at times advanced and sophisticated today about the electromechanical relay is a device that controls the voltage of the switch. Send over volts attached to the operating latching relays. Unlike other relay, the relay does not need to stick to the tension off. Take back the voltage is not over in the first position. It takes other measures to force them to return to power as operating or reset. Another type of relay will return to their original position once the course is deleted. The fact that the switch remains in position after beating pulse means that electricity demand is reduced, so a good way to save energy.
It would be very easy for you to understand and actually there is a small strip of metal attached to a relay that is used to rotate between the two terminals. The switch connects either the magnet or magnets. Two small coils of wire called a solenoid on the side of the magnet. There is an entrance to the switch with two output terminals. Switches used to activate a single circuit or off. This is called single stick relay coil. Current is passed through in one direction to the lock and released by exchanging the current in the opposite direction. A relay can also stick power control between the two separate circuits. This is known as dual coils attached because it uses two coils. Current circuits into a coil lock switch, and others in the coil to move back.
