A relay is a switch used to control a circuit either electronically or electromechanically. Relays consist of mainly five parts: The Electromagnet, armature, spring, two electrical contacts and a model frame. Some switches use an electromagnet as the electronic component. However, sometimes a manufacturer may use other methods to control the circuit such as solid state relays. Solid state relays have a sensor rather than the moving parts used in an electromagnetic switch. In solid state relays there are no contacts and are totally electronic. Relays are often used by a manufacturer where a safe low voltage circuit controls a high voltage circuit, but it isn't possible to have a direct connection to the high voltage electronic component. Do-it-yourselfer and engineers need them, in order to detect or to monitor abnormal electrical values. Relays can be used for a number of products, such as antennas, air conditioner, heat pumps, starter motors in cars or on telephone switchboards as well as in several industrial goods. If a higher current is being produced in the circuit, a manufacturer may use an electronic component that is similar to a relay called a contactor. A contactor can be used to control a large number of actions such as lighting in an office building, where the contactor works as the central control. On our marketplace you will find a huge range of relays and contactors. You can buy various types of relays, such as time relay, reed relay, latching relay or machine tool relay. We offer you relays from brands like Schneider Electric, Crouzet, TE Connectivity, Omron or Panasonic, so that you will definitely that relay that fit to your need and application. Extra information: Joseph Henry, Edward Davy and Samuel Morse are regarded as the inventors of the relay.
