  • Patent number: 4608466
    Abstract: Am improved switch is set forth. The switch has an insulating housing supporting a plurality of flexible contacts fashioned from a first conductive material selected to impart flexibility and spring action to the contacts. Accordingly, the contacts can be biased to engage and maintain contact with the switch rotor which is manipulated to produce the desired switching. Welded to each contact is a terminal connector extending to the exterior of the housing for connection to wires. The terminal connectors are fashioned from a second conductive material selected for strength and durability to prevent breakage.

  • Patent number: 4346269
    Abstract: A rotary switch has a detent mechanism and one or more switch sections. Each switch section has a rotor disc with annular conductive tracks thereon and four sets of stator contacts, two on each side of the rotor shaft and staggered to engage alternate conductive tracks. The switch section housing has two identical parts which snap together, each section carrying two sets of contacts. The stator contacts are mounted between ribs with an interference fit of the contact edges and the rib walls. The contacts are mounted with a set of contacts joined together and then the joining web is severed.
