The switch is sealed by an O-ring around a cylindrical extension that fits into a bore.  Look at the new one.  The O-ring is probably just stuck.  Get under two opposite sides of the switch with small screwdrivers and pop it out. 


What is it you're trying to accomplish by replacing the switch with a cover?

The function of the switch is twofold.  By telling the CDI when the bike is in neutral, the switch causes the rev limit to be lowered when the bike is out of gear (from 11,500 to ~7000), and tweaks the timing curve so that it has a better chance of passing sound tests.   IMO, it's more a matter of which one is more expensive.  The switch or its absence will not affect performance in any way.
