SEALED, ILLUMINATED ROCKER SWITCHES
ATTRACTIVE & RUGGED FOR WET & DUSTY ENVIRONMENTS
SEALED
ROCKERS
K3
The OTTO K3 rocker switch is a quality, precision switch designed
to comply with standards established for appliance, marine (ignition
protection) and off-road vehicles along with other demanding
applications where rugged rocker switches are required.
K3 sealed rocker switches snap into industry-standard panel
cutouts. Choose illuminated and printed legends, thru-panel
drain option and switching compatibility from low level to
20 amps.
The K3 offers a choice of LED, incandescent and neon
illumination. Legends can be stamped onto a non-illuminated
button, stamped onto an illuminated lens or laser etched into
the lens and backlit.
Available in standard and low level contact ratings, the K3
rockers will fit a wide range of applications. Expect a minimum
of 25,000 cycles at a full rated load of 20 amps resistive or 15
amps inductive. 100,000 cycles mechanical. A full complement
of switch operation is available including momentary and
maintained action in 2 or 3-position switches in SPST, SPDT,
SPTT, DPST and DPDT circuit arrangements.
OTTO can provide custom colors upon request. Value-added
assemblies with wire leads are also available. Please consult the
factory for assistance.
