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
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
