Specifications Subject To Change Without Notice
ATTRACTIVE AND RUGGED FOR WET & DUSTY ENVIRONMENTS
The OTTO P9 series pushbutton switches feature a contoured Dome
style pushbutton and share similar size and characteristics to the
OTTO P7 series. Major differences are plastic housing construction
and the availability of a shorting bar contact arrangement. There are
two button versions: low button profile and high button profile. The
P9 comes with a threaded case for hex nut mounting or with a snap-
in case. The switch series features short behind-panel depth. They
also offer excellent mechanical and electrical performance while
operating under severe conditions found in demanding applications.
The OTTO P9 Dome series is offered in dusttight and moistureproof
sealed construction. Expect a minimum of 25,000 operations at full
rated load of 5 amperes resistive or 3 amperes inductive; up to a
million operations in low signal switching.
Watertight sealing (IP68) submersible to 1 meter water pressure is
available. Add “W” suffix to the part number to specify IP68 rating.
The OTTO P9 Dome series is available in standard and low-force
double-break snap-action and non-snap shorting bar models. All are
momentary action. Special contact variations are available. High
contact pressure and unique contact design provide low contact
resistance for low level switching capability as well as full rated
service. Solder, PC Pin, and .110” Quick Connect termination options
are available.
Positive tactile feedback signaling the operator when the switch is
operated is available in snap-action models but not shorting bar models.
The OTTO P9 Dome series is a quality precision switch designed for
use in panels, control grips, computers, instruments, heavy equipment
and other demanding applications where attractive, rugged
pushbutton switches are required.
