The MOSFET you chose will probably fail. Using a 30V device on a 24V system is asking for problems. Go to a minimum of a 60V MOSFET and use a UIS, Avalanche rated one. R4 is very week for what you need to do, I would suggest something in the 10K range to swamp out any leakage in the Arduino. If the MOSFET is properly rated the flyback diode is not needed but ...

So here is the deal (I Kinda Solved It) so I took apart a 9V battery pack with a flip switch in it..... soldered some wired to it and now it works perfectly...... haha but I would still like the know the reason why the rocker switch module doesn't work. the only thing I can think of is the Voltage or Amp passed from the Switch Module isn't enough to power ...

It is difficult to determine from the diagram if the green wire is at the same voltage as the black wire supplying power to the Arduino board. Even if they are connected, it is difficult to say if the current is nominal. As there is a power supply of unknown design involved for both the Arduino and the float switch. This could cause unexpected results and ...
