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. They are totally sealed so the switch can withstand direct water spray and submersion, even during operation. They are designed to meet the international submersion specification level IP68. An optional panel seal is also 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 lens 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 cut-out size specified; other manufacturers require trial-and-error cut-out sizing.

Existing unsealed or sealed applications are easily upgraded to sealed functionality because the K series drops into existing panel cut-outs.

A choice of models are offered to handle power levels to 16 amperes, 1/2 HP and low level electronic switching applications.
