The Cole Series P3900 miniature P.C. termination rotary switch
is designed to provide the ultimate mechanical and electrical
reliability in instrumentation, industrial controls, medical equipment,
aircraft, computers, communication, weapons, and ground support
electronic equipment.
This precision switch is designed for high and low level switching,
engineered to meet the requirements of MIL-S-3786 and tested per
MIL-STD-202 as follows:
THERMAL SHOCK PER MIL-STD-202; METHOD 107, TEST CONDITION “B”
VIBRATION PER MIL-STD-202; METHOD 204, TEST CONDITION “B”
MEDIUM SHOCK PER MIL-STD-202; METHOD 213
HIGH SHOCK PER MIL-STD-202; METHOD 207
MOISTURE RESISTANCE PER MIL-STD-202; METHOD 106
EXPLOSION PROOF PER MIL-STD-202; METHOD 109
SALT SPRAY PER MIL-STD-202; METHOD 101, CONDITION “B”
The Series P3900 is available with 30°, 36° and 45° indexing and
one to six poles per deck. Self cleaning contacts are ideal for low
level switching and offer low contact resistance through the life of
the switch (25,000 cycles minimum). A hardened steel sprocket and
ball bearing detent mechanism provides smooth positive detent
action and mechanical life in excess of 100,000 cycles. Cole’s unique
terminal design and sealing technique prevents flux contamination
during wave soldering and cleaning processes. Internal plastic parts
are made of fiber filled plastic to prevent degrading and interior
contamination by plastic dust. Finally, superior construction, in
a clean room environment, ensures ultimate performance and
reliability from the Cole Series P3900 rotary switch.
