[TenTec] Cleaning Switches

[Mike Hyder -N4NT-]

If it is made like the bandswitch wafers, there is a disc on each side 
of the contacts.  The discs have holes about 1/8 or 3/16 inches in 
diameter into which one can spray ever so slightly little Cramolin 
contact cleaner (use DeoxIT DN5 Power Booster).  After cycling the 
switch from stop to stop several times, one waits until the cleaner has 
dried.  Finally a very quick spray of Cramolin contact lubricant is put 
into the wafers and the switch cycled some more times.  (Sorry I do not 
know the current designation of the Cramolin contact lubricant.)

If the shaft is binding where it passes through the mounting bushing, 
I'd suggest a small drop of light machine oil.

Does that answer your question?

73, Mike N4NT

|               I will be refurbishing a Triton IV soon.  The mode 
switch is stiff and erratic. How do I
|     clean and loosen this switch that seems to have a plastic cover 
over the contacts?  I
|     just briefly got to look at it and want to be prepared when the 
rig gets here.
