Victor,
Not so great info!! This info can not be accurately correlated to "in
service " use because it does not take into account environmental
conditions. Temperature, humidity, contamination (airborne and other
forms) vibration and various combinations will drastically alter the
"life" of the key pads.
This test can give a false feeling of security!
