P9 DOME PUSHBUTTONS SEALED DOME PUSHBUTTON SWITCHES 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 snapin 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. Snap-in case with .110" Quick Connect Terminals Standard Characteristics/Ratings: OPERATIONAL: Positive tactile feedback signaling the operator when the switch is operated is available in snap-action models but not shorting bar models.
