Different types of Relay with wiring connections. The relay is basically electromechanical switches these work with mainly electromagnetic field and mechanical arrangements, Relay is very important element in automation sector because of key of the controlling device .
#what is relay?
Relay is electromechanically switch.
Electromechanical that means electrical plus mechanical, there mechanical arrangement apart from the coil. It will be  work after energized the coil with induce the electro magnetic force near the coil.
#How many types of the Relay 
Basically four types of the Relay when used in industry sector.
Single Pole Single Throw.
Single Pole Double Throw.
Double Pole Single Throw.
Double Pole Double Throw.
  
#How dose it work 
The Relay is received the signal (in electrical voltage form)
from any control Unit or Control panel then energized the coil and also induce  the electro magnetic force and start the work with mechanical arrangement after that create the  switching from Normally closed to Normally Open Or Normally open to Normally Closed. So, finally we got the output the relay, As per requirement  we can use it.
