As the founding member of "Rip the Switches" society, I would like to
point out that the official "Larry the Mad Torquer" test was not an
accident
of misguided wrist muscles.  For years, I have been exercising and toning
my wrist muscles to be the official "MOTM mechanical integrity quality 
assurance engineer.  I take my role seriously and claim sole responsibility
for the quality enhancements announced by this manufacturer as the result
of my tests.

Please remember that the mechanical testing laboratory is supported by user
dues.  Please remit your 1999 dues as soon as possible if you have not done
so already.  Your support is appreciated.  In case you have forgotten,
annual
dues are $2 annually for each module in your system on January 1.

Seriously, thanks Paul.  I have always thought this type of tightening was
best
for switches.

Well, no pressure is placed on the base of the switch.  The bushing is not
pulled
away from the switch base.  Instead the nuts are tightened against each
other
putting all pressure on the bushing threads.  And, the nut on the back
holds the
lock washer against the back of the panel better that the switch base does.

MOTM subscribers,
Don't forget. Send those dues!
