The OTTO LP9 Lighted Dome series is a quality precision switch
designed for use in panels, control grips, instruments, heavy
equipment and other demanding applications where attractive,
rugged, lighted pushbutton switches are required.
The LP9 series offers a positive tactile feedback signaling the operator
when the switch is operated with the added benefit of reliable LED
illumination. The LP9 series offers four button versions; flush and
raised profile with either a glossy or matte finish. Also comes
with a threaded case for hex nut mounting while providing a short
behind-panel depth.
The LP9 series is constructed to meet the IP68 watertight seal.
Expect a minimum of 25, 0000 operations at full rated load of 5
amperes resistive or 3 amperes inductive; up to 500,000 operations in
low level switching.
The LP9 series are momentary snap action double break switches,
available in standard and low operate forces. The LED is available in
5 colors and has the ability to accommodate 2 and 12 VDC
