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.
