Removed the screws holding the grinder head on and the screw holding the back piece to the main body then just pulled the grinder apart. Replaced the switch parts and reversed the disassembly procedure. Only concern was holding the brushes away from the armature.

Using phillips screw driver, remove the black housing cover at the end of the grinder where the electrical cord is located.
Locate the black plastic piece that is the mechanism that turns on/off the grinder (it slides and is spring loaded).
Push the mechanism up, and in turn you will see where the switch is located the \'notch \' becomes accessible. This is the ON position.
While holding mechanism up in the ON position, insert new switch so the switch \'hook\' goes into the mechanism \'notch\'
Release mechanism while holding switch into position.
Re-attached black housing cover.
Boom goes the Dynamite!
