SEALED DOME PUSHBUTTON SWITCHES
MOMENTARY ACTION, ATTRACTIVE & RUGGED FOR WET & DUSTY ENVIRONMENTS
The P9 Dome series pushbutton switches feature a contoured
dome style pushbutton and share similar size and characteristics
to the P7-D series. Major differences are plastic housing construction
and the availability of a shorting bar contact arrangement. There
are two button versions: flush button profile and raised button
profile, and two bezel versions: standard and small. 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 and offers excellent mechanical and electrical
performance while operating under severe conditions found in
demanding applications.
The P9 Dome series is offered in dusttight and moistureproof
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 to IP68S and IP69K is available simply by
adding a “W” suffix to the part number.
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.
