The defining characteristic of the IP68 switches is their particularly good protection against dust and water. The IP scale defines switches of this type as dustproof and protected against permanent submersion. A switch of this protection class is therefore dustproof and waterproof.
Switches certified according to the IP68 standard are available in various versions: toggle switches, rocker switches, rotary switches, F-N-R switches and more. IP68 switches are specially sealed against environmental influences and are therefore suitable for outdoor use under adverse conditions or in sensitive industrial or medical equipment.
