Electrical Wiring in the Home/wiring new switch to unisaw table saw

I want to replace the switch on my table saw so i bought a new one and am confused as to how to wire it up as it seems to be different. It is wired for a 220v circuit, and my new switch has the ability to be wired for either 110v or 220v. My main confusion is the white wire connected to two screws on the old switch by a metal tab in between them.


Jason looks like a Woodstock non magnetic switch     in the link above it gives you the diagrams for dual voltage    the old switch just had the neutral  IT SHOULD BE ANYWAY   white wire jumped across the other two nc and no poles  but we dont care about the old one,     just the new one and I think that is the link above     if not it is close  if not    then we need the diagram cause I cannot see on the new one what anything is    

Next a non magnetic switch is dangerous    if the power goes out,  you trip the breaker with a knot in a hunk of wood  when the power is restored so is the saw,     no de-latching  it is like a light switch  

I would suggest you use a fused disconnect to protect the motor,   breakers protect wire,   

then use a magnetic motor starter type switch   I know it didn't have one    but they aint going to lose a finger          I would also suggest tying in a foot or knee operated jumper to the magnetic coil    on the magnetic on off switch         

so it is fused disconnect    then magnetic switch   then an "emergency switch"  knee or foot operated   and tie that in series with the coil of the magnetic switch     

But if you want to go this way  I think I got you the right thing     if not I need the switch data so I can find the diagram or I need the diagram scanned in    you can use my personal email if it is easier for you,  but I would spend the extra money     to be safe     how much is a finger or hand?

Because they made it that way dont make it right,   make it right for YOU
