I am trying to get fimilar with electrical components. I did some BG research on relays. Does this make sense. 1.My systems needs a switch to control a component so that is why I need a relay. It is a micro-switch that will move towards its position(Normally open or Normally Closed) depending on the incoming power over the coil based on how it is wired to NO and NC to the component I am trying to control with the switch. 2. My basic relay diagram below controlling a light(Wired for normally open) -No power switch is off, Power switch is on. Switch(Rated at different Power)-<>-----Relay----<>-----Light(At a different Power) incoming power-->Power of switch-----------------<>-----Relay----<>-----power of light 3. If hooked up in Normally open and I power it on do I even need a switch to turn the light on if it goes on autmatically? If so then would I hook it up thru Normally closed to use a switch to turn it on and off?? This is all new to me so lead me in the right direction so I can pick and choose relays for a project!! even the most basic!! Does both my statements make no sense?????
