[R-390] Power Switch

[chuck.rippel at cox.net]

You can also take the power switch apart relatively easily, clean the 
contacts with a contact file and re-install it.  Putting a .05 @ 1KV 
across the switch might help supress the arc but as we've discussed here 
before, the inrush on the radio is fairly substantial.

Besides removing the screws securing the switch assy to the FUNCTION 
cluster, there are also what appears to be aluminium rivets holding the 
switch body together.  These have a very low pitch thread on then and 
can be backed out.  Use a knife blade under the head, and pack them away 
just enough to get some purchase on the head.  Pull with a set of needle 
nose or small pliers; they will try and twist as they are pulled out. 
"Assist" the twisting action to remove them.  There are also 2 snap tabs 
on the switch, carefully disengage those and the switch can be taken 
apart like a clam-shell.

CAREFUL!!!  Some of the parts inside are spring loaded and are capable 
of flying to parts unknown if allowed.  Take a small contact file and 
clean both sides of the switch contacts.  Re-assemble and enjoy.
