Re: [DML] Re: DIY Door Light Switch Upgrade: Magnetic Switches

I may be wrong, but I believe these are also neodymium magnets.  At  
least that's what Wikipedia claims.

This site:

	http://www.magnet4less.com/index.php?

sells magnets and also lists how many pounds of force the magnet  
exerts, presumably when in contact with metal.  I think the ones I  
have are in the range of 9 pounds.  They have 1" x 2" cylinders that  
exert 175 pounds.  Might be a little overkill. :)
