    Abstract: A reversible snap-action switch including a drive member and a switch-actuating driven member connected by a lost motion coupling. The relative position between the drive and driven members is shifted by substantially the lost motion distance as the drive member moves the driven member through a switching zone and then reverses its direction to return to its original position. In each direction of movement a bidirectional accelerating means imparts a snap-action motion to the drive member. This motion is coordinated with the position of the driven member so that switching occurs during the snap-action motion in each direction of movement, thereby inhibiting any hesitation in making or breaking the switch contacts. The invention also includes a cement-free mounting for the switch contacts.

    Abstract: The switch comprises a body carrying fixed electric contacts and a movable member rotatably mounted in the body. The body has curved ribs of identical radius which extend around a barrel and define between them a plurality of free spaces containing electrically conductive balls. At least two of the spaces are partly occupied by the fixed contacts. An electrically conductive ring is interposed between the balls and elastically yieldable members carried by the base of the movable element. The conductive ring is put in contact with the fixed contacts through the balls, which constitute moving contacts, and closes the switch electrically when the movable element is rotated relative to the body. The edges of the ribs constitute abutments for the balls.

    Abstract: A switch having planar contacts and a rotary brush engageable with the contacts to perform a switching function has printed circuit board mounting lugs integral with planar contact circuitry. The lugs allow mounting of the switch to the edge of the printed circuit board and is of miniature size suitable for use with a watch stem of an electronic wristwatch. Tactile feel and positive detent of the switch rotor is provided with a resilient beam which detents against the irregular surface of a cam provided on the rotor. The cam has an offset finger that resiliently deflects a return spring which returns the switch rotor to an off position providing only a momentary switching function when the rotor is manually rotated and then released. The switch parts are designed for stackable assembly without a need for fasteners. The switching function, in this instance, is associated with resetting of the hour and minute time display.

    Abstract: In a polyphase transfer switch for tap-changing regulating transformers the cooperating fixed and movable contacts of each phase are arranged to form a pattern in the shape of a sector of a circle. The movable current-carrying contacts are hingedly supported by the movable main contacts. Due to the presence of a lost motion connection the current-carrying contacts are separated prior to separation of the main contacts, and on account of this lost motion connection cooperating current carrying contacts are brought into engagement only after the main contacts are brought into engagement.
