MOMENTARY ACTION, SEALED SUB-SUBMINIATURE PUSHBUTTON SNAP-ACTION SWITCHES
The P7 series incorporates OTTO’s patented double break
design in a significantly smaller package than the P1 series.
These subminiature switches embrace today’s technology
requirements by allowing for a large number of switches to fit
within a faceplate.
The long life snap-action design is protected from the
environment by a silicon rubber boot, operating on a patented
“rolling sleeve” principle that gives long sealed life and
smooth operation.
The P7 series is designed to meet the requirements of MIL-
PRF-8805 including low level switching (10mA @ 30mV) with
power switching up to 5 amps at 28VDC as well.
A variety of mounting styles are offered to best match the
application. The P7-1, P7-2, P7-7 and P7-8 case styles feature
a swaged bushing shape to allow press fit installation in
aircraft flight control and hand grips and similar applications.
The other styles feature threaded bushing mounting. The
P7-3 case style has a front panel bezel, while the P7-5 and
P7-6 have conventional bushings for rear panel mounted
installations. Silver or black bezels are standard. Other
colors available on special order.
Pushbuttons are available in a choice of nine colors. Excellent
tactile feedback assures the operator that contact transfer
has been made.
A choice of MIL-SPEC and commercial versions of these
switches are offered: Moistureproof and dusttight to IP64
and MIL-PRF-8805 Design 2 or watertight to IP68S and to
MIL-PRF-8805 Design 3.
