Military Qualified Half Inch Enclosed Rotary Switch
Cole's Series M1800, Military Style Rotary Switch is designed to
provide the ultimate mechanical and electrical reliability in instrumentation,
medical equipment, aircraft, computers, communication, ordnance,
as well as ground support electronic equipment.
This M1800 Series switch is designed for high and low level switching,
and is qualified to meet the requirements of MIL-S-3786/20 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 36, 45, 60, and 90 degree indexing
with one or two poles (see Circuit Diagram). They include fixed
stops, sealed and unsealed styles, PC or solder lug terminals,
RFI & EMI protection, and a .125" or .250" dia. shaft. The shaft
is provided with either a single flat or a screwdriver slot.
Unique design construction features include: all terminals on
the rear, self-cleaning contacts for low level switching, and
low contact resistance through the life of the switch (25,000
cycles min.). The detent mechanism provides smooth positive detent
action and a mechanical life in excess of 50,000 cycles. In the
M1800, the terminals and commons are molded in diallyl phthalate
thermosetting plastic. COLE seals the housing, plastic, terminals,
and commons with a special process to eliminate flux contaminants
from seeping inside the switch during wave soldering and cleaning.
The M1800 switch is built in a clean atmosphere, as are all COLE
products, to prevent contamination during assembly.
These and many other features will provide the ultimate in mechanical
and electrical reliability, during the life of the switch.
The M1800 qualified switches may be ordered by the Military part
number or by the COLE part number.
