Description
Clare’s Molded Ultra-Mini DYAD
TM
is well suited for small,
signal switching applications. The small size lends itself
to surface mountable applications; working well on higher
density PC boards. The Molded Ultra-Mini DYAD
TM
has
sputtered ruthenium contacts and an extraordinary seal
strength achieved by a patented laser sealing of the leads.
In low level or dry switching environments, switches
typically exceed 1 billion operations. In addition, the
molding process provides a solid plastic outer shell. This
plastic shell provides superior mechanical strength,
eliminates concerns over handling glass switches, and
provides an ideal solution for high speed, automated
assembly environments.
Ordering Information
A complete part number is represented by the digits to
the right. For example, CM5S1030 is a MOLDED ULTRA-
MINI DYAD™ with a minimum operate value of 10NI and
a maximum of 30NI. Refer to the switch operating
specification charts for available ranges. Special ranges
are available upon request.

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.
