An electrical rocker switch having a clam-shell like in which a rocker is pivotally mounted. A unitary multi-function operating assembly fabricated from spring stock materials which operates as an over-center spring to establish two rest positions for the rocker. A trifurcated second end of the operating assembly provides springs to urge the contact assembly into intimate engagement with the boss on the underside of the rocker. Cross-members of the operating assembly bear movable contacts which selectively engage fixed contacts on the housing to complete external electrical circuits connected to the operating assembly and fixed contacts. An additional housing can be placed about the clam-shell like housing to seal the switch from the environment.
