SEALED, ILLUMINATED ROCKER SWITCHES
LOW COST, SNAP-IN ROCKER FOR WET & DUSTY ENVIRONMENTS
K1/K2
SNAP-IN
ROCKERS
The K series rockers are rugged, high performance sealed
switches designed for use under severe conditions found in
marine, appliance, heavy equipment and industrial control
applications. Sealed to IP68S with an optional panel gasket
available.
The K1 series is offered in single pole configuration while the
K2 series is available in single and double pole configurations.
Both series offer illuminated models. Illumination can be
independent or dependent of the switch position or a
combination of both. A choice of red, green, clear or amber
colored lenses are offered in illuminated models. Illumination
options include incandescent, LED or neon light sources.
Mounting is simple and quick; snaps into panel from the
front. The OTTO snap-in design supports a variety of panel
thicknesses with just one cutout size specified.
A choice of models are offered to handle power levels to 16 amps,
1/2 HP and low level electronic switching applications.
OTTO can provide custom colors upon request. Value-added
assemblies with wire leads are also available. Please consult
the factory for assistance.
