A silent electric switch means comprising a body having first and second ends and a cavity therein, a switch member rotatably received in the cavity of the body having first and second ends respectively proximate to the first and second ends of the body, and a control means for rotating the member between terminal and intermediate positions about a longitudinal axis. The first and second ends of the switch member are provided respectively with first and second electrical contact means with the first contact means electrically connected with the second contact means, first and second plates respectively mounted on the first and second ends of the body each having respective electrical contacts, the contacts of the first and second plates being respectively electrically engaged by the first and second contact means of the switch member when the switch means is in either of its terminal positions and disengaged when the switch means is in its intermediate position. A cylindrical surface of said cavity, having an arc of at least 180 DEG , provides the only axis about which the switch member can pivot.
