WIRING IN A RELAY. WHY AND HOW.

[@dharley189]

Hi Eric. I was in car repair 50 years. Seldom see many uses for fifty terminal except in two speed radiator fan apppications.
Since retiring I work in mowers. See a lot of use on mowers in the safety controls used to kill engine.
I have twisted that fifth spade off when not used.
Also there are a lot of diodes used to protect computer controlled circuits. No need on the example you gave.
I was taught “Relay uses small current switch to control High current load”. Very good video explaining the purposes. Thanks. Del

For sure, many more uses than what I skimmed over. Thank you for the comment and for watching! Cheers.
