The figures given below show the actual design of a simple relay. Relay Construction It is an electro-magnetic relay with a wire coil, surrounded by an iron core. A path of very low reluctance for the magnetic flux is provided for the movable armature and also the switch point contacts. The movable armature is connected to the yoke which is mechanically connected to the switch point contacts. These parts are safely held with the help of a spring. The spring is used so as to produce an air gap in the circuit when the relay becomes de-energized.

Morg Show you how you can connect a jcq-3f relay to the Arduino, so I did not face even in theory. Amazon Drive Cloud storage from Amazon. Common is connected to one End of the Load that is to be controlled. Thank you in advance!



How to use a Relay Relays are most commonly used switching device in electronics. Let us learn how to use one in our circuits based on the requirement of our project. Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. Our relay here has 5V trigger voltage, but you can also find relays of values 3V, 6V and even 12V so select one based on the available voltage in your project. Make sure the load you are using falls into this range.
