for small switching signal applications. This switch has
sputtered ruthenium contacts and an extraordinary seal
strength, achieved by a patented laser sealing of the glass.
In low level or dry switching environments, both switches
typically provide >1 billion operations. The switches have
hermetically sealed contacts and offer a wide range of
available magnetic sensitivities.

Absolute Maximum Ratings are stress ratings. Stresses
in excess of these ratings can cause permanent damage
to the device. Functional operation of the device at these
or any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for extended period may degrade the device and effect
its reliability.
(See detailed specifications for more information.)
