RELAY SCHEMATIC EXPLANATION

How Relays Work | Relay diagrams, relay definitions and
In electromechanical relays, the coil accomplishes this function. A relays Output Circuit is the portion of the relay that switches on the load and performs the same function as the mechanical contacts of electromechanical relays. Solid-state relays, however, normally have only one output contact.

Top: Looking straight down, you can see the spring contacts on the left, the switch mechanism in the middle, and the electromagnet coil on the right. Bottom: The same relay photographed from the frontose you want to build an electronically operated coolingsystem that switches a fan on or off as your room temperaturechanges.

Identify Terminal Pins of A Relay Without Reference to
Relays that normally used in electronic circuits are SPDT and DPDT types due to their flexibility in controlling circuit switching. In the next section, a demonstration on identifying the pins of a relay from SPDT or DPDT type without referring to its datasheet will be illustrated. A 5-pins type relay,

PDF fileTechnical Explanation for Solid-state Relays Introduction What Is a Solid State Relay? A Solid State Relay (SSR) is a re lay that does not have a moving contact. In terms of operation, SSRs are not very different fr om mechanical relays that have moving contacts. SSRs, however, employ semiconductor switching elements, such as thyristors,

Arduino + Relay Explanation
No a solid state relay will look to the Arduino like an LED. Not a lot to explain, it shows a transistor driving the relay. The relay coil is the square with the line through it. The transistor is the symbol with three connectors labelled base, emitter, collector. R1 shows a resistor, and D1 is a diode.
