Rugged pushbutton switches with new contoured dome styling. There are two design versions: flush dome and raised dome button profile. They also offer excellent mechanical and electrical performance while operating under severe conditions found in demanding applications.

The OTTO P3-D Dome series features dusttight and moisture- proof or watertight sealed construction. Add “W” to your part number for watertight seal. Expect a minimum of 100,000 operations at rated load of 10 amperes resistive or 5 amperes inductive; up to a million operations in low signal switching applications.

The OTTO P3-D Dome series is available in standard and low operating force double-break snap-action 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.

The OTTO P3-D Dome series is a quality precision snap-action switch designed for use in panels, control sticks, computers, instruments, heavy equipment and other demanding applications where attractive, rugged pushbutton switches are required.
