Flaky hi/low beam switch -- anyone replaced it?

The hi-low beam headlight switch on my 2001 is flaky. Sometimes when I press the toggle forward to select high beam it turns off for a second -- obviously not a good thing. If I press the switch in a slow and very precise manner it never flakes out, which makes me 99% sure the switch is the culprit. I opened the switch up to see what was wrong but it's hard to see inside it. If I replace the whole switch assembly does it just plug into the wiring harness using connectors, or do I have to solder it in? If anyone can provide detailed steps for replacing it that would be much appreciated.

 

take it apart and clean the contacts.. road grime and dirt make cause this and also check the contacts for wear/ corosion.
