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.

The magnetic force (expressed in NI, AT or Ampere Turns) required to cause the reed switch contacts to
close is called the pull-in or operate value.
