(solenoid) nearby. When the solenoid electrified, the lever would be interested because of the magnetic force that occurs in the solenoid so that the switch contacts will close. By the time the flow is stopped, the magnetic force will be lost, the lever will return to its original position and re-open switch contacts.
How it works is similar to how the relay contactor. Where there is normally open dannormally close, which will work if the coil currents listrik.Relay given above is normally open. Where the switches are not connected. Furthermore, the coil will be electrified which will cause the switch to close or close., His principles remain the same, ie, using the benefits of electric current generates a magnetic field.
The working principle of electromechanical relays are defined as follows:
• Tools that use electromagnetic force to close (or open) switch contacts.
• The switch is actuated (mechanically) by power / electrical energy.
In typically use a relay driven by a DC current which is equipped with a diode in parallel with the windings and the-best is mounted on the anode voltage (-) and the cathode voltage (+). It aims to anticipate the jolt of electricity that occurs when the relay switch from on to off position so as not to damage the surrounding components.
Application of a relay can be used vary according to the needs or the need to pay attention to keperluan.Penggunaan relay voltage controller and power relay download switch current / voltage. Body size is usually stamped on relay.itu was his explanation of How it Works Relay And Relay Principles.
