A sealed rocker switch includes a button having a lever. A coil spring coaxial with the lever and enclosing a portion of the lever forces a plunger against an actuator that rocks to place a spring blade in contact with blade contacts to operate the switch. The blade contacts are snapped into the case of the switch to maintain the blade contacts in a desired position, and are potted with a potting compound to make a seal. The actuator may be shaped in one of several ways to provide maintained contact, momentary contact, or a combination of these. A groove in the lever supports an O-ring against the case to seal the switch at the button end.
