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 seal 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.
