SEALED DOME PUSHBUTTON SWITCHES
MOMENTARY ACTION, ATTRACTIVE & RUGGED FOR WET & DUSTY ENVIRONMENTS
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 P3-D Dome features dusttight and moistureproof or
watertight sealed construction (add “W” to your part number
for watertight seal). 100,000 operations at rated load of 10
amps resistive or 5 amps inductive; up to a million mechanical
operations in low level switching applications.
The P3-D Dome 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 P3-D Dome 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.
