LOW COST, SNAP-IN TOGGLE FOR WET & DUSTY ENVIRONMENTS, 1 & 2 POLES
The K4 series snap-in toggle switches are rugged, high
performance sealed switches designed for use under severe
conditions found in marine, appliance, heavy equipment and
industrial control applications. They are totally sealed so the
switch can withstand direct water spray and submersion, even
during operation. Sealed to IP68S with an optional panel
seal available.
The K4 series is offered in single and double pole configurations.
Toggle action includes 2 and 3-position, momentary and maintained
operation in a combination of 13 variations.
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.
Existing unsealed applications are easily upgraded to sealed
functionality because the K series drops into existing panel cutouts.
A choice of models are offered to handle current from 16 amps to
low level electronic switching levels.
Features:
• Withstands direct water spray
• Sealed to IP68S
• Fits industry standard panel openings for drop-in
replacement of panel sealed & unsealed switches
• Snap-in feature accommodates a wide range of
panel cutouts
• Switches up to 16 amps
• UV & solvent resistant
• Withstands extreme shock & vibration
• Legends & illuminated function indicators available
• 2 & 3-position, momentary, maintained action
and center OFF
• RoHS & WEEE compliant
