Super Noob EE question:
Here is my quick draw-up of my SPST switch circuit schematic.
I know I probably did not do this right, but if it gets the idea across, then thats good enough for me atm.
The right boxed section is a connector where I showed the power pin (V1 @ 12V), trigger pin, and ground pin (chassis).
The left side is a (hopefully correctly drawn) pull-down resistor setup with SPST switch (SW1) and standard 10k resistor (R1).
Does this 10k resistor (R1) act as a current limiter in this circuit?
On the top of that, I added a 1k resistor (R2A OR R2B OR R2C) in series with the SPST switch (SW1) because i was wondering if it could be used as a "current limiting resistor".
I was also wondering if it matters where the resistor goes, whether its before or after the switch, shown by R2A & R2B & R2C.
What are the differences (if any) between positions R2B and R2C?
Also, I think this becomes a voltage divider right? where the voltage will be 10/11 * 12V at the trigger pin when the switch is closed?
If I didnt have resistor R2, then what voltage would the trigger pin see with the switch closed? 12V?
Can it "make sense" at all to put in this R2 resistor in this circuit? What uses can it have?
