S3900 SERIES Miniature Multi-Deck Solder-Lug Rotary Switches T he Cole Series S3900 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 S3900 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 S3900 rotary switch.
