Other features include gold over nickel-plated beryllium copper contacts, four-point wiping contact design, positive detent action for shock resistance and deep "V" slots to locate any operation probe.
* Wiping contacts: Connectors broadly divide into two types based on the design of the wiping contacts:
Featuring eight Powerpole circuits integrated into a blind mate housing, the two-row horizontally oriented connector uses proprietary flat wiping contacts. It can be configured with eight standard length contacts or six standard length and two pre-mate ground contacts.

These switches feature wiping contacts, a leaf spring mechanism and a flame retardant glass-filled nylon housing and plunger for rugged, reliable operation in heavy-duty applications such as industrial machinery, material handling, packaging and automation.
In addition, Sarah features compression "activation ridge" technology, which ends the need for conventional high-pressure wiping contacts. The technology makes it possible to apply, on demand, the required force to achieve optimum contact pressure.
The lower current ratings are made possible by the incorporation of self-cleaning wiping contacts, which ensure longer switch working life for the entire D3V family.
