Circuit Assembly Tutorials || How to Build a Latching Relay Circuit (with explanation)

This video demonstrates how to build a latching relay circuit with a double pole double throw relay. It includes a detailed explanation of how such a circuit (as well as relays in general) work. The meaning, functionality, etc., of the normally open, normally closed, and common relay pins are discussed during the explanation.

Parts List:
-- Double Pole Double Throw (DPDT) Relay:
A 12V DPDT Relay was used in the video (RadioShack # 275-249) )
-- Normally Open Momentary Button (from, e.g., Sparkfun, Adafruit, Jameco, etc.)
-- Normally Closed Momentary Button (RadioShack # 275-1548)
a led
-- 220 to 1K resistor (for the led)
-- 1N4001 diode (or e.g., 1N5819 schottky)
-- hookup wire
-- power supply capable of producing the requisite voltage/current needed to energize the relay's coil (12V DC in the case of the relay used in this video)
-- and a breadboard
