SEALED ILLUMINATED DOME PUSHBUTTONS
The LP7-D series pushbutton switches feature a contoured
round dome style or square pushbutton. While sharing similar
size and characteristics to the P9 series, the LP7-D offers
added durability with its anodized aluminum alloy case.
Button versions include flush or raised round dome in glossy or
matte finish and raised square in matte finish. The switch series
features short behind panel depth. It also offers excellent
mechanical and electrical performance while operating under
severe conditions found in demanding applications.
The LP7-D Dome series offers one million mechanical
operations and an electrical life of 25,000 operations.
The LP7-D series is manufactured to the highest standards
and built to withstand harsh environments, offering anodized
aluminum alloy cases with seal options of dusttight to IP64
or watertight to IP68S. The LP7-D series offers long life LED
lighting in a variety of colors and can accommodate 2 & 12VDC
power.
The LP7-D Dome series is a quality precision switch designed
for use in panels, control grips, computers, instruments, heavy
equipment and other demanding applications where attractive,
highly ruggedized pushbutton switches are required.
