If you need competitively priced quantities of any kind of relay switches shipped anywhere in the world, Area51 can deliver.
Relays are electrical switches that are made to open and close by other electrical circuits. Relay switches at their most basic level consist of a coil and an armature. The coil is made up of a conductive material looped multiple times which creates an electromagnetic pull when an electrical charge is applied. The armature is a small bar made of a magnetically attracted material, such as soft iron. The armature is mechanical in nature and usually held in its normal position by a spring. When a flow of electricity is applied to the relay and enters the coil, the electromagnetism created within it attracts the armature to make a point of contact with it, thereby completing the electrical circuit. When the electrical current is removed, and the electromagnetism of the coil subsides, the tension of the spring returns the armature to its natural position, breaking contact and switching the relay off. Relays have the ability to control a higher powered output circuit with the input of a lower powered circuit. In this sense, a relay switch can be broadly considered a type of electric amplifier.
Relay switches have evolved to have many variations on its basic functions. Latching relays, which are also known as ‘keep’ relays, are relay switches which are ‘bistable’. This means that when no electrical charge is applied, the relay stays in one of two positions possible in its relaxed state. When the charge ceases, the relay stays in the last position it was in. This keeps the armature in constant state of contact, and an additional electrical charge is required to move the relay to the other position. Basically, one pulse of energy will switch the relay to one position, and another is required to switch it back to the opposite position. These kinds of relays are energy efficient because it only required a momentary electrical charge to switch them and keep them switched, and another momentary electrical charge to switch back. In the result of a power outage, it will stay contacted in the position it was intended.
A reed relay consists of a set of contacts which are contained within a glass tube. Inside the glass tube there either exists a vacuum, or the presence of inert gas. This protects the contacts from atmospheric corrosion. The coil is wrapped around the glass tube and the contacts within the tube close when the electrical charge is applied to the coil. Reed relays can handle switching speeds that are faster than the average relay switch. A mercury wetted relay is a certain type of reed relay in which a the contacts of the relay are soaked in mercury which makes the lowers the electrical resistance of the contacts.
Contactor relays are strong, durable relays that are used for the switching of electric motors, usually to start them. High amounts of current are usually required for this and the contact points are usually made of pure silver.
A solid state contactor relay is also a very strong and durable relay used for the switching of electric motors, electric heating, and lighting in which on / off cycles often occur. They require a heat sink to efficiently dissipate heat and contain no moving parts that could wear out. Solid state relays such as these provide the same function as an electromechanical relay, but are more reliable then a traditional relay. These relays are controlled by microprocessors.
Relay switches are very important in today’s age of computers and electronics. Because of their ability to control circuits of high voltage with low voltage signals, they are very useful in certain kinds of modems. Relays are also capable of performing logic functions and are more useful than semiconductors in control panels where the relay switch failure mode properties are used for safety critical logic functions.
Protective relays are similar in that they monitor the operating status of an electrical circuit and activate circuit breakers when a fault in the circuit is discovered. Protective relays are complex electromechanical assemblies usually consisting of multiple coils with predictable and selectable operating constraints. They are devices of a considerable mechanical complexity and are rapidly being replaced by numerical relays, which are microprocessor controlled and provide a cost effective alternative which is also convenient in application.
