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.
