SRC Devices’ Overmolded Ultra Mini DYAD 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 Overmolded Ultra Mini DYAD has sputtered ruthenium
contacts and an extraordinary strength achieved by a patented laser sealing of the leads. In
low level or dry switching enviroments, 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.
