The P7 series incorporates OTTO’s patented double-break design in a
significantly smaller package than the P1 series. These subminiature
switches allow the switch density today’s technologies require in
control grips and panels.
The long life snap-action design is protected from the environment by
a silicon rubber boot, operating on a “rolling sleeve” principle that
gives long sealed life and smooth operation.
The P7 series is designed to meet the requirements of MIL-S-8805
including low level switching (10 mA @ 30 mV) with power switching
up to 5 amps at 28 VDC as well.
Avariety 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 series
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 had been made.

offered: Moistureproof and dusttight to IP64 and MIL-PRF-8805
Design 2. Watertight to IP68. Watertight to MIL-PRF-8805 Design 3.
