Miniature Multi-Deck Solder-Lug Rotary Switches
Cole's Series S3900, miniature solder lug rotary switch is designed
to provide the ultimate mechanical and electrical reliability in instrumentation,
industrial controls, medical equipment, aircraft, communication, weapons,
as well as ground support electronic equipment.
This S3900
Series switch is designed for high and low level switching, and
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 switches are available with 30, 36, 45, 60, and 90 degree indexing
and one to six poles per deck, (see Circuit Diagram).
Unique design construction features include: self-cleaning contacts
for low level switching and low contact resistance through the life
of the switch (25,000 cycles min). Hardened steel sprocket and ball
bearing detent mechanism provide smooth positive detent action and
a mechanical life in excess of 100,000 cycles. In the S3900, the
terminals and commons are molded in diallyl phthalate thermosetting
plastic sealed between the plastic and the metal terminal with a
special process to eliminate flux contamination seeping inside the
switch during soldering and/or cleaning processes.
Rotors and non-shorting rings are molded of thermo-plastic glass
filled to eliminate contamination by transferring plastic particles
to the contact system during the life of the switch. The S3900 switch
is built in a clean atmosphere, as are all Cole products, to prevent
introduction of contaminants during assembly.
These and many other quality features will provide the ultimate
in mechanical and electrical reliability, during the life of the
switch.
