Precision formed phosphor
bronze contacts are selec-
tively gold plated. Phosphor
bronze has excellent
strength characteristics
which help the connector
absorb load deflection
movement of a PC board
while maintaining sufficient
contact force for good elec-
trical connection. Bifurcated
cantilever beam contacts
provide redundant contact.
