LOW LEVEL momentary action, attractive & rugged for wet & dusty environments
The P9L Dome series low level 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 P9L 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 P9L Dome series is offered in dusttight and moistureproof
sealed construction. One million mechanical operations and an
electrical life of 500,000 operations at 50mA resistive.
Watertight sealing is available simply by adding a “W” suffix
to the part number to specify IP68S rating.
The P9L 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. 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.
