The diagram shows an inner section diagram of a relay. An iron core is surrounded by a control coil. As shown, the power source is given to the electromagnet through a control switch and through contacts to the load. When current starts flowing through the control coil, the electromagnet sta...
The development of relays was initiated in the period 1809. As a part of the invention of the electrochemical telegraph, the electrolytic relay was found by Samuel in the year 1809. Thereafter, this invention was asserted by the scientist Henry in 1835 so as to make an improvised version of ...
This change of state in the contacts occur whenever a small electrical signal is applied i.e. whenever a small amount of current flows through the relay, the contact changes. This is explained through the figures below- Abovefigure shows the switch in NO contact position. In this figure, pri...
Relay is one kind ofelectrically operated switch. The main function of this switch is to control the circuit electronically & electromechanically by connecting and disconnecting the circuit. The applications of relays include control panels, automation of building, manufacturing to control the power. The...
1. A switch comprising two electrical contacts (46, 47) arranged respectively on a support, and a movable plate (6) connected to a third contact, each switch being located inside a case, said case being composed of a base (2) made of a magnetic material and a cover (3) made of a ...
Turn on the ignition switch, and then use your ear or stethoscope to listen to control the sound of suction in the relay HKE, or feel the vibration of the relay HKE with your hand. If so, it means that the relay HKE is basically working normally. Caused by the reason; otherwise, it...
CPU - The Core of a Switch A switch uses the distributed architecture, including forwarding and control planes. The forwarding plane implements Layer 2 and Layer 3 forwarding; the control plane implements forwarding control. As shown in Figure 17-1, the control plane uses the universal embedded ...
