Definitions

  • ABSTRACT 8 Claims 4 Drawing Figures MULTISECTION ROTARY WAFER TYPE SWITCH ASSEMBLY WITI-I INTERLOCKING STATOR AND ROTOR SECTIONS SUMMARY OF THE INVENTION BRIEF DESCRIPTION OF THE DRAWINGS
  • the invention is illustrated diagrammatically in the following drawings wherein:
  • FIG. 1 is a front view of a rotary switch construction of the type described
  • FIG. 2 is a section along plane 22 of FIG. 1,
  • FIG. 3 is a plan view of a switch member with parts removed
  • FIG. 4 is an enlarged partial sectional view illustrating the connection between the adapter plate and one of the stator sections.
  • a switch shaft is indicated at and may be received within an exteriorly threaded bushing 12.
  • the bushing 12 maybe integral with a front plate or housing 14 having a positioning projection 16 on the front thereof.
  • the bushing 12 will extend through an opening in an instrument panel and a nut or the like may be screwed on the threaded area of the bushing to fasten the switch section to the instrument panel.
  • a conventional knob may be placed on the shaft 10 for operation of the switch.
  • the housing 14 may have rearwardly extending sides 20 which mount detent balls 22.
  • the balls 22 cooperate with a detent wheel 23 to control rotary position of the switch.
  • the details of the detent mounting arrangement may be similar to that shown in U. S. Pat. Nos. 3,293,382 and 3,411,377.
  • the rear of the housing 14 may be closed by an adapter plate 24 which may be attached' in a suitable manner to the rear of the sides 20.
  • switch sections there are a plurality of switch sections, in this case three, indicated at 26, 28 and 30.
  • the mechanical portions of the switch sections will be generally similar and will include stators 26a, 28a and 30a, and rotors 26b, 28b and 30b.
  • the rotors and stators may be conventionally constructed relative to the electrical connections therebetween.
  • Each of the stators may have a pair of interlocking hook members extending outwardly from the periphery.
  • the hooks are indicated at 32 and, as shown in FIG. 3, are unevenly circumferentially spaced apart such that the adjacent switch sections can only be snapped together in a particular manner. Details of the interlock between the stators are shown in U. S. Pat. No. 3,290,456.
  • each of the hooks 32 will snap over a projection 34 on an adjacent stator to prevent relative axial movement between adjacent stator sections.
  • Projecting pins 35 on each stator interlock with mating openings or holes 37 in the adjacent stator to provide an interlock against rotary movement between the adjacent stators. Again, this construction is detailed in U. S. Pat. No. 3,290,456.
  • each of the stators is interlocked with an adjacent stator to prevent relative axial and rotary movement between stators.
  • FIG. 4 details the interlock between the adapter plate 24 and the closest stator, in this case stator 26a.
  • the hook 32 of stator 26a fits over a projection 36 on the adapter plate 24 which is of a size and shape generally the same as that of the hook portion 34 of each of the stators, thus necessitating no change in a stator to interlock it with the adapter plate.
  • Dimples 38 similar to the pins 35 on the stators, interlock with openings 37 in the stator 26a to prevent rotary movement between the adapter plate and stator 26a.
  • the interlock, both axial and rotary, between the adapter plate and the stator 26a is effectively the same as the interlock between each of the adjacent stators.
  • Rotors 26b, 28b and 30b have identical rearwardly projecting hubs 42.
  • the hubs and sockets may have identical cross sectional areas, for example flatted, square, rectangular, triangular or the like.
  • the hubs may be formed in what is known as the double D cross section, with the sockets having the same configuration.
  • the particular cross section is not important. What is important is to provide a nonrotational interlock between adjacent hubs and sockets so that the rotors will turn in unison.
  • the rear end 46 of the switch shaft 10 may have the same cross sectional shape as that of the hubs 42. Thus, the rear end 46 of the shaft may fit into the socket 44 of rotor 26b. Accordingly, rotoary movement of the shaft 10 will be effective to turn all of the interlocked rotors.
  • the shaft 10 has a fixed length, but can accomodate a switch construction made up of any number of separate switch sections, each having similar rotors and stators.
  • the fixed length shaft 10 can operate as many rotors as there are positioned in the switch construction.
  • New switch sections, each having stators and rotors similar to the already mounted switch sections, can simply be added by snapping the stators on the hooks of the previously mounted stator and interlocking the rotors to the rotor of the previous switch section.
  • a single shaft may operate any number of switch sections with the advantage that the switch shaft may be manufactured in a single size.
  • a rotary switch construction including a plurality of concentric, axially spaced switch sections, each section having a rotary portion and a stationary portion, means on each stationary portion for interlocking with the stationary portion of an adjacent switch section, means on each rotary portion for interlocking with the rotary portion of an adjacent switch section, thus interlocking all rotary portions for simultaneous rotation, including a hub extending outwardly from one side of each rotary portion and a socket recessed intothe opposite side of each rotary portion,
  • the structure of claim 1 further characterized by and including a detent mechanism for controlling the rotary position of said shaft and said rotary portions.
  • the structure of claim 1 further characterized by and including an adapter plate for attaching said detent mechanism to one of said stationary portions.
