What is a relay switch?
Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized. When a relay contact is Normally Closed (NC), ...
How does an armature work?
One end of the armature is attached to the metal frame, which is formed so that the armature can pivot, while the other end opens and closes the contacts. Contacts come in a number of different configurations, depending on the number of Breaks, poles and Throws that make up the relay.
Is a solid state relay the same as an electromechanical relay?
Although Solid State Relays accomplish the same results as Electromechanical Relays, the physical structure and functionality of Solid State Relays is different from that of Electromechanical Relays.
What is relay used for?
Relays are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices except for small motors and Solenoids that draw low amps.
How do magnetic relays work?
When the magnetic field is strong enough, the attracting force of the opposite poles overcomes the stiffness of the reeds and draws them together. When the magnetic force is removed, the reeds spring back to their original, open position. These relays work very quickly because of the short distance between the reeds.
What is a solid state relay?
With solid-state relays (SSR), there are no contacts and switching is totally electronic. The decision to use electromechanical or solid state relays depends on an application's electrical requirements, cost constraints and life expectancy. Although solid-state relays have become very popular, electromechanical relays remain common. Many of the functions performed by heavy-duty equipment need the switching capabilities of electromechanical relays. Solid State Relays switche the current using non-moving electronic devices such as silicon controlled rectifiers.
Why does a relay have a number of parts?
A relay, though, has a number of parts because it converts electrical current to mechanical movement and uses the mechanical movement to change electrical contacts. Uses the electromagnet to move a mechanical arm (armature) Uses a spring to return the armature to a relaxed state when the energizing electrical current stops.
What is relay switch?
A relay is a mechanical switch that is turned on and off by an electromagnet. A basic relay consists of an electromagnet and contacts. The electromagnet changes the position of the common contact from the normally closed contact to the normally open contact. By Douglas Krantz.

What is the most important part of a relay?
The most important part of the relay is the electromagnet. It is a soft iron core wounded by a coil. It doesn’t have the magnetic property initially. But it can acquire the properties of a magnet when a voltage is applied to the coil winding.
Why are relays useful?
Relays are useful when there is a need to control large current or voltage by a low power signal. They come with different functions and types. It generally consists of electromagnets that control the circuits electromechanically to make or break the load circuit.
How does a spring work?
The spring can keep the contacts separated until the electromagnet is energized. It has normally closed, normally opened terminals and a common terminal. When the coil is not energized, the normally closed terminal is connected to a common terminal or to the armature, and the normally opened terminal is left free.
What is an automatic stabilizer?
Automatic stabilizers are one of its applications where a relay is used. When the supply voltage is other than the rated voltage, set of relays sense the voltage variations and controls the load circuit with the help of circuit breakers. Used for the circuit selection if there exists more than one circuit in a system.
Why do relays have a yoke?
Yoke: It is a small metal piece fixed on a core in order to attract and hold the armature when the coil is energized. Spring (optional): Few relays don’t need any spring but if it is used, it is connected to one end of the armature to ensure its easy and free movement.

So, when a metal winded with a copper wire and driven by the sufficient power supply, that metal can act as a magnet and can attract the metals within its range.
Is a slider always connected to either of the contacts?
So, the contact is always made to either of the terminals. A slide switch can be considered as its example. The slider is always connected to either of the contacts i .e., a closed path always exists all the time if both the terminals are connected to a circuit.
Why is the movable armature being altered?
Since the movable armature is placed within its range, it gets attracted to that magnetic field created by the core, thus the position of the armature is being altered. It is now connected to the normally opened pin of the relay and external circuit connected to it function in a different manner.
