Clare’s Molded Ultra-Mini DYADTM 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 DYADTM 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 ULTRA­MINI 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.
