  • US Patent:
    46200770, Oct 28, 1986
  • Filed:
    Feb 19, 1985
  • Appl. No.:
    6/703197
  • Inventors:
    John Zdanys - Elkhart IN
    Tony J. Zaderej - Elkhart IN
    Matthew A. Robbins - Elkhart IN
  • Assignee:
    CTS Corporation - Elkhart IN
  • International Classification:
    H01H 1708
  • US Classification:
    200331
  • Abstract:
    An integral switch connector with remote actuator has a plurality of conductive terminals disposed within a switch housing. A slide member is remotely biased to make or break contact between contact arms to switch voltage between terminals. A connector disposed within switch housing provides connection to a remote apparatus. The remote actuator has a snap-action feature, to bias the slide member independently of the speed of movement of the manual biasing means. Movement of the actuator assembly biases a non-conductive actuator rod disposed within a non-conductive sleeve, to bias the slide member within the switch housing to make or break electrical communication between terminals. A spring disposed between the slide member and the switch housing breaks electrical contact between terminals should the actuator rod fail. A link coupling provides a removable connection between rod and sleeve at a location between actuator and switch assemblies.

    Durward H. Priebe - Paso Robles CA
    Norman C. Weingart - Elkhart IN
    John Zdanys - Elkhart IN
    Jack A. English - Elkhart IN
  • Assignee:
    CTS Corporation - Elkhart IN
  • International Classification:
    H01H 1524
  • US Classification:
    200 16D
  • Abstract:
    A machine insertable miniature DIP switch (10) comprises a housing (12) insert molded about a plurality of terminals (40). The terminals (40) are oppositely disposed pairs having interior portions (44) located within housing chambers (30) formed by transversely extending walls (20), with the ends of the pairs of terminals separated by an open area (A) comprising a depression. An actuator (60) includes an upward extension (64) above a top plate (62) with a contactor receptacle (66) located therebelow, a depending detent wall (68) with a detent protrusion (70) on one side of the actuator, and an oppositely disposed depending actuator side wall (72). The detent protrusion (70) is received by detent openings (22) within the associated transverse wall (20), top plate extensions (63) are positioned over the associated transverse wall, and the oppositely disposed actuator side wall (72) is positioned for engagement with a shelf (24) located in the associated transverse wall. A contactor (80) comprises a U-shaped upper portion (82) received in the actuator receptacle (66) to effect a self-leveling, load equalizing coupling, and a lower portion comprising a plurality of outwardly extending legs (84), each leg (84) having an arcuate foot (86, 87) at an end thereof. The arcuate feet (86, 87) engage the interior terminal portions (44) whereby lateral displacement of the actuator (60) effects constant pressure slideable engagement of the contactor (80) with the terminals (40) to complete or open an electrical circuit therebetween, without the contactor feet (86, 87) engaging any housing material.

  • US Patent:
    46545220, Mar 31, 1987
  • Filed:
    Feb 10, 1986
  • Appl. No.:
    6/828586
  • Inventors:
    Robert F. Gornick - Edwardsburg MI
    John Zdanys - Elkhart IN
  • Assignee:
    CTS Corporation - Elkhart IN
  • International Classification:
    G01D 534
  • US Classification:
    250231SE
  • Abstract:
    A miniature position encoder (10) provides means for transducing angular changes in shaft (60) position to an electrical output representing the Gray code. The miniature position encoder (10) comprises an annular housing (12) having an aperture (14) with a bushing (20) disposed therein opposite an open end (18) of the housing (12), a plurality of light emitting diodes (50) disposed in non-linear alignment in a substrate (40) mounted adjacent the bushing (20), and a metallic shaft (60) journalled within the bushing opening (15) and having a metallic logic disk (70) secured at one end, the logic disk having a plurality of radially spaced and angularly limited openings representing the Gray code. A window disk (110) is mounted within the housing cavity (28) and adjacent the logic disk (70) for the purpose of restricting the amount of light emitted by each of the light emitting diodes (50), and a plurality of phototransistors (100) are mounted upon a substrate (90) positioned at the open end (18) of the housing and adjacent the window disk (110), with a cover (120) enclosing the open end of the housing. Rotation of the shaft (60) effects rotation of the attached logic disk (70) which modulates the light passing through the openings within the logic disk, whereby the Gray code is transmitted as an eight bit parallel output code received by light receptors (100).

  • US Patent:
    39447600, Mar 16, 1976
  • Filed:
    Apr 8, 1974
  • Appl. No.:
    5/458505
  • Inventors:
    John Zdanys - Edwardsburg MI
    William L. Kelver - Cassopolis MI
  • Assignee:
    CTS Corporation - Elkhart IN
  • International Classification:
    H01H 1502
    H01H 2704
  • US Classification:
    200 6BB
  • Abstract:
    A switch assembly provides a plurality of slide switches. Each switch employs a flexible guide rod cantilevered within a common housing providing a first contact. A second contact is biased into electrical contact with each guide rod and an insulative cam carried by a switch actuator is supported by each guide rod for rectilinear movement therealong in an interference path with the second contact to separate the second contact from the guide rod. The flexible guide rod is movable with respect to the second contact and provides the means to align the switch actuator and the cam in an interference path with the second contact. Each switch actuator provides a pair of side walls enclosing a respective guide rod and second contact suspended therebetween.
  • Multiple-Function Switch With Automatic Return

  • US Patent:
    43202675, Mar 16, 1982
  • Filed:
    Jun 30, 1980
  • Appl. No.:
    6/164781
  • Inventors:
    James E. Greve - South Bend IN
    John Zdanys - Edwardsburg MI
  • Assignee:
    CTS Corporation - Elkhart IN
  • International Classification:
    H01H 900
    H01H 2176
  • US Classification:
    200 4
  • Abstract:
    A multiple-function electrical switch has an automatic return to an initial position upon release of the shaft (60). An annular drive (70) mounted upon the shaft (60) has a rotary contactor (100) and momentary switch contacts (90,92) secured thereto, and a torsional spring (110) is mounted in a cover (36) enclosing one end of the housing (11). As the shaft is rotated, a tongue (78) on the driver (70) engages the torsional spring (110) which will effect return of the driver and shaft to its initial position upon release of the shaft. The tongue (78) is received in a pocket (56) located in the cover (36) such that the shaft (60) may be moved axially at only one rotational position, such movement effecting engagement between the momentary switch contacts (90,92) and terminals (44,46) disposed in the cover. The housing is insert molded about a collector (12) and terminals (14, 16, 18, 20, 22), the collector having a stepped portion (28 ) engaged by the rotary contactor (100) to provide a detent as the user rotates the contactor from a first selected terminal to a second selected terminal.

  • Filed:
    Feb 17, 1998
  • Appl. No.:
    9/025015
  • Inventors:
    James E. White - Warsaw IN
    Jeffrey L. McCurley - Elkhart IN

  • Assignee:
    CTS Corporation - Elkhart IN
  • International Classification:
    G01B 714
    G01B 730
  • US Classification:
    3242072
  • Abstract:
    An extremely reliable and effective position sensor is provided at low cost for determining the relative position of a mechanical linkage with respect to a reference point. The position sensor includes a rotor or bracket which is mechanically coupled to the linkage and contains at least two magnets on opposite walls adjacent a channel opening. The opposing magnets are formed with first and second sloped or ramped sections which produce produce variable magnetic fields as determined by the geometric profile of the magnets. One or more detectors are positioned in the air gap between the opposing magnets. As the linkage is moved, the rotor or bracket moves with respect to the detector causing a change in the strength of the magnetic field detected by the detector whereby the detector determines the position of the movable linkage.
