Definitions

  • a slide selector switch including a plurality of independently removable slide assembly modules mounted within a housing, with each module having electrical contacts adapted to engage an etched printed circuit board at the rear of the housing.
  • Each module includes a non-signal carrying slide supporting bar and at least one slide which supports the electrical contacts and is adapted for positive detentingto multiple switch positions along the bar.
  • Each module is otherwise provided with a targeting arrangement-whichproduces a highly visible display of an indicia associated with the selected switch position.
  • the slide selector switch enables a high number of positive circuit selections to be made from a small panel area.
  • the slide assembly modules are readily removable from the switch housing for replacement, and such removal does not disturb the circuitry of the circuit board or wiring attached thereto, since, the modules haveno signal carrying member other than the electrical contacts.
  • the present invention relates to a slide selector switch adapted for providing a high switching capacity from a small panel area. More particularly, the invention concerns a slide selector switch having a large number of independently removable slide assembly modules mounted within a housing, with each module having electrical contacts thereon adapted to engage a circuit board mounted at the rear of the housing.

  • circuit board is illustrated as being mounted in spaced relation to the rear of the switch housing by means of spacers 37 and screws 38 suitably secured through corresponding openings formed in the comers of the circuit board.
  • Circuit board 20 is fabricated by conventional techniques, having a central core 46 of insulating material on either side of which are provided suitable conductive areas laid down by etching.
  • the circuit board is provided on its front or inner face with a plurality of longitudinal electrical circuit paths 41a-41f spaced.
  • Conductive paths 41 extend substantially across the face of the circuit board and converge and terminate at a connector block 40 formed on the right-hand side of the circuit board, as viewed in FIG. 5.
  • Connector block 40 is adapted to receive a standard connector 42 such as that illustrated in dotted outline in FIG. 5.
  • a plurality of electrical contact areas or pads 43 are also provided on the front face of the circuit board, arranged in rows 44a-44f, interspersed with corresponding paths 41a-4lf.
  • Thenumber of pads 43 in each row corresponds to the number of positions each slide of the assembly module is designed to provide.
  • each full length slide assembly module is adapted to have twelve switch positions.
  • the interspersed conductors are arranged so that a row 44 and a conductive path 41 are provided corresponding to each slide assembly module of the switch. Also, all the pads 43 occupying the number one position in each row are vertically aligned. Accordingly, each of the 12 vertical columns of pads 43 are juxtaposed with electrical circuit paths or strips 45 provided on the back surface of the circuit board. Circuit paths 45 are vertically oriented, as viewed in FIG. 5, and extend substantially the full depth of the circuit board, converging and terminating at the edge of a connector block 47 formed at the bottom of the circuit board. Connector block 47 is adapted to receive and make contact with a standard connector 50 such as that illustrated in dotted outline at the bottom of FIG. 5.
  • one or more holes 48 is formed through the core of the circuit board between each pad 43 nd its corresponding conductive path 45.
  • Conductive material or layers 47 are provided in these openings, for example deposited by a conventional process known as plating through, whereby electrical contact is made between all the pads of a given column and a corresponding conductive path 45. Therefore to complete a circuit between a selected conductive path 41 and a selected conductive path 45 it is merely necessary to bridge the gap between the appropriate pad 43 and the path 41. This function is achieved by slidable electrical spring contacts carried by a slide 52 on each slide assembly module 18.
  • one slide assembly module 18 is particularly illustrated, comprising a module base 51, a slide 52 and a module indicia strip 54.
  • the module base 51 is preferably formed of metal and the slide assembly is formed of insulating material. This gives good strength and shielding characteristics to the module base and minimizes the possibility that stray currents will reach the base.
  • Base 51 includes a pair of spaced apart longitudinal bars 55, 56 joined near their extreme ends by cross members 57.
  • the longitudinal bars and cross members are formed as a solid molding, stamping or casting, although the base could be fabricated of assembled members, if desired.

  • slide 52 is formed of symmetrically molded upper and lower sections 61, 62 joined together by rivets 64 so as to encompass longitudinal bars 55, 56.
  • An operating lever 66 is attached to the under side of lower section 62 of the slide, also by rivets 64.
  • sections 61, 62 are each formed with a rear recess 67 therein having a width substantially corresponding to the width of longitudinal member 55, and having a depth slightly greater than one half the thickness 'of longitudinal .bar 55. Therefore, with the upper and lower sections of the slide sandwiched together around bar 55, the slide is smoothly and laterally movable with respect to the bar.
  • upper and lower sections 61, 62 are each formed with a recess 69 near the front thereof, adapted to surround front longitudinal bar 56 when the sections are sandwiched together.
  • Recesses 69 further include inner grooves 71 which are adapted to provide a housing for an elongate detent spring 74, when the sections are sandwiched together.
  • Spring 74 has right angle bends formed at its extreme ends and is adapted to fit snugly over the opposite'ends of the slide.
  • the spring is otherwise formed with a protrusion 76 at the center thereof, adapted to seat within corresponding detenting pockets 77 of longitudinal bar 56.
  • one end 78 of the operating lever extends outwardly beyond the other portions of the slide assembly module so that it can be gripped by an operator for moving the slide laterally with respect to'the module base.
  • protrusion 76 of detent spring 74 is successively indexed along the longitudinal bar 56, successively dropping into the detenting pockets 77 formed therein.
  • the protrusion positively engages the corresponding detenting pocket and retains the slide in that desired position.
  • Protrusions 80 are provided at the rear edge of the upper and lower sections of the slide so that a contact mounting block 82 is formed when the sections are sandwiched together.
