Exceptional
Solutions for Military Applications |
Cole Instrument prides itself
on producing switches that are able to meet and exceed the strictest
Military standards. In harsh environments, where reliability is
a matter of life and death, Cole switches excel in providing the
utmost in function and dependability. Demanding situations call
for Cole switches.
The following are custom switch solutions designed for challenging
military applications
 |
This
custom encoded, push-to-actuate, rotary switch is specially
designed for applications requiring low weight,
high reliability,and very low acoustic noise
when activated from position to position.
The noise is undetectable at distances as close as 6 feet,
yet the switch gives excellent detent feel.
The switch is in a 1/2-inch square plastic body
with a behind panel length of less than 1 inch. Its
low weight is particularly significant when it is used in
portable equipment that must be carried by
personnel over long distances. |
This
is another custom design where a customer presented a challenging
and unique requirement: a coded BCD rotary pull/push
switch with 10 positions and an "ON-OFF" detented
switch.
The "ON-OFF" switch is operated by pulling or pushing
the shaft a minimum of 0.200 inches to the detented mode.
The major challenge was to create this multi-mode,
multi-function high reliability switch in a 0.675 Max. Diameter
body and 1.750 Max. behind panel. |
The customer had very demanding requirements, and the switch
we delivered met all their requirements. |
| This
3900 Solder Lug switch has a custom heavy-duty detent.
The switch is pull-to-turn, and tease-proof.
The customer's problem was other vendors could
not supply a switch with the desired feel. COLE was
able to manufacture a detent that met their requirements perfectly. |
The customer had very demanding requirements, and the switch
we delivered met all their requirements. |

Exceptional
Solutions for Aerospace Applications |
Cole Instrument is an industry leader
in producing switches that answer the exacting demands of the engineer
and the end user. Cole switches provide the highest quality and
service life for a wide range of aerospace needs, while ensuring
the best possible “feel” for pilots in commercial and
military situations.
The following are custom switch solutions designed for demanding
aerospace applications:
 |
This
switch assembly is three switches in tandem
with two PC mount rotary switches and one push-button (SPST)
switch.
The two PC mount switches are actuated by concentric
shafts and have independent detent systems. The outer
shaft (0.25 Dia.) actuates the front switch. The inner
shaft (0.125 Dia.) actuates the rear rotary switch, and also
actuates the SPST switch with a pushing action.
All this in a 0.865 diameter body and less than
2.5 inches behind panel length.
This is ideal for applications where multiple switching
functions with high reliability are required, and
where space is at a premium. |
Yet another custom
design where COLE was presented with a challenging and unique
requirement.
In this case it's a tri-axial shaft actuating three
separate functions: |
|
Actuates a regular 12 position (30¡
indexing) rotary switch located in the front of the
total switch assembly. |
| 2 |
Middle shaft |
| 0.250 Dia. |
Actuates a 32 position (11.25¡ indexing)
optical encoder, with a two bit quadrature code.
It is located in the center of the total switch
assembly. |
|
Actuates a SPST push-button switch
requiring 0.150 Max. travel to be activated.
It is located at the rear of the total switch assembly. |
|
Cole Instrument designed the total switch assembly
with a 1.0 inch diameter body and 3.0 inches Max. behind panel
length.
All switches have solder terminals. |
