SEALED, ILLUMINATED SNAP-IN TOGGLE
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.
