philo mech's video: 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 If there are any questions, please leave them in the comments and I will do my best to help.
