A relay is a form of electrical switch that is operated by electromagnet which changes over the switching when current is applied to the coil.These relays may be operated by switch circuits where the switch cannot take the high current of the electrical relay, or they may be op...
The switch has a positive wire from the fuse box. It then has a wire from other terminal of the switch to a coil terminal on the relay. Once this coil circuit is closed with 12 volts, the electromagnet inside the relay is energized and a set of contacts will close. The “input” ...
Reed relays contain a reed switch, a coil for creating a magnetic field, an optional diode for handling back EMF from the coil, and an encapsulating package with connection terminals. In many ways, a reed relay, if used correctly, is a near perfect device with a low-resistance metallic ...
We should all know the function of the relay. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, resulting in an electromagnetic effect, and the armature will be attracted by the electromagnetic force. Under the action, it overc...

a relay, a magnetic field needs to be created that is capable of closing the reed switch contacts. Reed switches can be used with permanent magnets (for example, to detect doors closing), but for the reed relays, the field is generated by a coil, which can have a current passed through...
Ⅱ. How does Relay Works? The relay's functioning principle is depicted in the diagram below. When the switch is closed, a voltage is provided to both ends of the coil, and a current flows through the coil, producing an electromagnetic effect. The armature will overcome the return spring'...
