Abstract: An encoder assembly is disclosed which comprises a drum-like rotor having an outer circumference and a central bore with at least one slot, and a plurality of encoder elements arrayed around the outer circumference of the drum-like rotor. The assembly further comprises a shaft having a diameter sized to fit into the central bore, and having a flattened key which is configured to fit into the at least one slot. The rotor and shaft fit into a housing having an inner section sized to receive the drum-like rotor and encoder elements. The inner section has an opening along one side such that the inner section incompletely encloses the circumference of the rotor. There is also at least one spring contact locatable within the housing such that it can make contact with the encoder elements through the opening in the inner section of the housing.

Abstract: A device for electrically connecting the conductors on a first PC board to the conductors on a second PC board includes a housing having a mounting surface for mounting on the first board, an exposed surface opposite the mounting surface, and a pair of opposed side walls. A plurality of channels open through the exposed surface, each having an interior defined between the interior surfaces of the side walls. A compliant contact element, formed as an integral conductive element, is disposed in each channel.

Abstract: A rotary switch includes a plurality of switching terminals exposed within a chamber in a housing. A fixed planar contact member, having a plurality of spring contact arms, is mounted in the chamber above the terminals. Each of the contact arms is movable out of the plane of the contact member to contact an associated one of the terminals. Each of the contact arms includes a cam follower, at least two of the cam followers being equidistant from the center of the contact member. The cam followers are operatively engaged, in a predetermined sequence, by camming elements extending axially from the bottom surface of a rotor mounted in the chamber above the contact member. The equidistant cam followers are engaged by camming elements that are spaced from the center of the rotor by a distance equal to the distance separating the equidistant cam followers from the center of the contact member.
