   I have a Milwaukee 12v variable speed tool with a bad control board.   
   Rather than replace the board, I'm planning to just use a switch for   
   single (full) speed.  But the switches that I have & will fit are AC   
   only.  So, I'm thinking that I'll use the switch to control a MOSFET   
   that will do the heavy lifting.  I just want to make sure that I'm not   
   missing anything.   
      
   The plan:

   The MOSFET is IRF3205 (Rdson of 8 mohm)   
      
   I don't think that I need a switch-gate resistor, or do I?   
      
   Thanks, Bob
