NEW YORK, NY--(Marketwire - 01/28/11) - After touching 30 year highs to kick
off the New Year, silver prices have slumped in recent weeks. Most of the
selloff appears to stem from the idea that greater global economic stability
will make the precious metals market less attractive as an investment.
Silver, however, is as much an industrial metal as it is a precious metal,

for a garmin is a square push button switch on upper right corner. If
someone could open it up for you, you will see a small round push button
assembly soldered on the edge of the board. Dirt or carbon deposit could
have gotten in the middle of the 2 contacts, what I used to do is to use a
surgical knife to open up the cover of the push button, and scrape those
contacts clean. |
