Forming part of the OTTO P9 Series, this black body rubber push switch cover is suitable for use with Sealed Dome Push Button Switches. The OTTO Black Raised Domed Rubber Boot is suitable for use with panels, control grips, computers, instruments and other demanding applications. KEY FEATURES • Multi-Use Rubber Switch Cover • Dust Tight & Moisture Proof • Available in Two Button Heights OTTO P9 Rubber Boot is designed to withstand extreme shock and vibrations.


Raised Dome with Threaded Case - Momentary action switches, suitable for wet & dusty or harsh environments.

The P9 Dome series pushbutton switches feature a contoured dome style pushbutton and share similar size and characteristics to the 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 P9 Dome series is offered in dus ttight and moisture proof sealed construction. One million mechanical operations and an electrical life of 25,000 operations at full rated load of 5 amps resistive or 3 amps inductive.

Watertight sealing is available simply by adding a “W’ suffix to the part number to specify |P688 rating. The 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 0.110’ 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 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.
