Definitions

  • the present invention relates to a switch suitable for use as a remote control switch for electrically operated rear-view mirrors of a motor vehicle. More particularly, the invention relates to a switch having switch elements comprising a pressure sensitive rubber sheet which becomes conductive only when and where it is pressed (hereinafter referred to as a "pressure-sensitive conductive rubber sheet” or, more briefly a “rubber sheet”.
  • Each of a pair of motor-driven mirrors mounted on a door, a fender or the like, of a motor vehicle has a respective electric motor for driving thereof, said electric motors being controlled by means of a switch inside the vehicle so as to adjust the direction of inclination, horizontal or vertical, of each mirror.
  • the switch for controlling the motor-driven mirrors is required to have the functions of actuating each of said two electric motors of each mirror independently, and reversing the polarity of the electric power supply thereto. Also, the switch should be easy to mount in an instrument panel or the like.
  • This previous switch comprises a housing, an operating member disposed within said housing at a predetermined clearance from the inner walls of said housing, said operating member being adapted to rock from its neutral position in mutually perpendicular directions, two switch elements disposed between a pair of plate-form electrodes via a pressure conductive rubber sheet and arranged in pairs at the four intervening positions, and a switch for reversing the polarity of a power supply is constituted by said switch elements.
  • the previous switch has a considerable depth which cannot be reduced because the operating member is rockably disposed within the housing and the switch elements are disposed between the operating member and the four inner walls of the housing. Also the switch is not very easy to mount in an instrument panel or the like. Furthermore, its design does not facilitate assembly thereof and does not provide a satisfying response in use because the operating member has almost no stroke and does not have a click-action.
  • U.S. Patent No. 4,029,915 discloses a switch comprising an insulating board arranged in a housing, and a plurality of stationary contact elements. Each of these elements are formed of a pair of film electrodes and arranged around a specific central position on the insulating board. A conductive rubber sheet forms switch elements together with the stationary contact elements. A key arranged tiltably to the rubber sheet drives the switch elements by means of pressing surfaces. Furthermore, a spring provides a resettable trend at the button.
  • the present invention provides a multi-position electrical switch comprising a housing, an electrically insulating base board disposed in the bottom of said housing, printed circuit electrodes formed an arranged on said base board to provide a pair of electrodes constituting fixed contacts of a respective switch means at each side of a rectangle, a pressure-sensitive electrically conductive rubber sheet extending over said printed circuit electrodes so as to form switch elements for making and breaking electrical connections between the fixed contacts of the respective switch means upon application and release of pressure thereto respectively, a supporting plate disposed over said rubber sheet, having a ball of a ball-and-socket joint disposed generally centrally with respect to said rectangle, said supporting plate having a plurality of openings therein, and operating button having a socket and being tiltably mounted on said ball to form therewith said joint, the face of said operating button facing said supporting plate being formed in the shape of a frustum of a pyramid having its notional vertex on the vertical axis of said ball-and-socket joint and having four faces having raised pressing surfaces formed
  • the switch of the present invention has a relatively flat, thin and shallow depth form which can be readily secured in a relatively small space such as in an instrument panel of a motor vehicle.
  • the use of a tiltable operating button having projections for preventing the simultaneous closing of switch elements other than the desired ones at any given moment with the operating button being displaced against the biasing of elastic portions and returned to its original position thereby provides a more positive feel in use and ensures smooth operation even after use for a considerable period of time.
  • Figs. 1 to 11 show a switch according to the present invention
  • Figs. 1 to 11 show a switch according to the present invention comprising a housing, 1 an electrically insulating base board 2 ( a printed circuit board) which also serves as the base plate of the housing 1. Disposed within the housing 1 is a power supply polarity reversing switch S 1 and another switch S 2 for changing over between right hand mirror R operation and left hand mirror L operation.
  • the switch S 1 comprises, for example, eight switch elements A to F ⁇ as shown in Fig. 9.
  • Several pairs of generally film-form electrodes 3 a and 4 a to 3 f ⁇ to 4 f ⁇ , serving as fixed contact elements of the switch elements A to F ⁇ , are printed around a specific central position 7 on the printed circuit board 2 in a pectinated shape.
  • the film electrodes 3 a and 4 a to 3 f ⁇ and 4 f ⁇ are disposed to occupy substantially the whole of the upper and lower, right and left areas of the printed circuit board 2.
  • the single rubber sheet 5 is common to all the fixed contact elements.
  • the pressure-sensitive conductive rubber sheet 5 is, for example, made of silicone rubber and metal particles. It is normally non-conductive and becomes conductive upon pressure being applied thereto.
  • the eight switch elements A to F ⁇ are disposed on the surface of the base board 2 and these switch elements A to F ⁇ are connected by printed conductors 6 so as to form two switch means for reversing the polarity of electric power source. That is, in Fig. 9, the four switch elements A , B , E and F form one switch means (switch means for vertical adjustment) and the four switch elements C , D , E ⁇ and F ⁇ form the other switch means (switch means for horizontal adjustment).
  • the arrangement of the switch elements A to F ⁇ on the base board 2 is illustrated in Fig. 8.
  • a supporting plate 8 as shown in Fig. 3, is disposed on top of the rubber sheet 5.
  • the supporting plate 8 is fixed at its periphery to the housing 1.
  • an operating button 11 is supported on a ball-and-socket joint 9 provided approximately in the centre of the supporting plate 8 so that the operating button 11 can be tilted with respect to the rubber sheet 5.
  • the operating button 11 has a square shape, for example as seen in the plan view shown in Fig. 1, and is adapted to apply localised pressure to the rubber sheet 5 when any of four operating portions thereof comprising: an upper portion 11 a , a lower portion 11 b , a left-hand portion 11 c and a right-hand portion 11 d as viewed in Fig. 1, is pushed. As shown in Figs.
  • the section of the operating button 11 facing the pressure-sensitive conductive rubber sheet 5, that is, the lower part of the button has the shape of a frustum of a pyramid having its vertex on the vertical axis of said ball-and-socket joint 9 which serves as a point of support, and has four faces 11 e , 11 f , 11 g and 11 h , as well as four intersection lines where adjacent faces meet.
  • Each of the four sloping faces 11 e to 11 h of said frustum has two pressing surfaces 12 a and 12 b , 12 c and 12 d , etc. slightly protruding therefrom.
  • pressing surfaces 12 a to 12 h correspond to said switch elements A to F ⁇ as follows:
  • the pressing surface 12 a corresponds to the switch element A , the pressing surface 12 b to the switch element F , the pressing surface 12 c to the switch element E , the pressing surface 12 d to the switch element B , the pressing surface 12 e to the switch element F ⁇ , the pressing surface 12 f to the switch element C , the pressing surface 12 g to the switch element D and the pressing surface 12 h to the switch element E ⁇ .
  • each of the four sloping faces 11 e to 11 h of said frustum of a pyramid corresponds to two switch elements.
  • a plurality of generally complementary through holes 8 a is provided in the supporting plate 8 opposite respective ones of the pressing surfaces 12 a to 12 h .
  • the ball and socket bearing mounting 9 supporting the button 11 consists of a sphere 10 provided at the side of the plate 8 and a sphere retainer 13 provided at the button 11 side.
  • the sphere 10 has a plurality of radially projecting pins 10 a extending in cross shaped arrangement towards respective ones of sloping faces 11 e to 11 h of the frustrations of the button 11.
  • Split grooves 13 a each having a narrow width slightly smaller than the diameter of the pin 10 a and elastically deformable to receive said pins 10 a are formed at the side of the retainer 13.
  • the button 11 is thus subject to a resilient return biasing force for always returning it to its central neutral position by means of the interaction of the split grooves 13 a , and the pin 10a.
  • the switch S 2 is for selectively connecting the above-mentioned switch S 1 with either the right-hand mirror R or the left-hand mirror L and is constructed as follows:
  • the switch S 2 comprises two circuits and six contacts.
  • Contact patterns l , m and 14 a to 14 d corresponding to the six contacts, are printed near one end (upper portion as viewed in Fig. 7) of the board 2.
  • the slide block 15 is provided with movable contacts 16 a and 16 b corresponding the contact patterns l , m and 14 a to 14 d .
  • a pair of push buttons 17 a and 17 b respectively corresponding to the right-hand mirror R and the left-hand mirror L are disposed on both sides of the slide block 15 in the direction of its slide.
  • the driving end of each push button is engaged with each of taper portions 15 a and 15 b formed on both ends of the slide block 15.
  • Numerals 18 a and 18 b represent balls for positioning the push buttons 17 a and 17 b .
  • Figs. 1 to 11 is a hybrid switch comprising said switch S 1 including the eight switch elements A to F ⁇ and said changeover switch S 2.
  • a connector 19 shown in Fig. 2 for externally leading the contacts l , m and 14 a to 14 d in the changeover switch S 2 to the exterior (the mirrors R and L ).
  • electric motors M 1, M 2 are provided for horizontally and vertically driving the right-handed mirror R
  • electric motors M 3, M 4 for vertically and horizontally driving the left-handed mirror L .
  • the switch elements D and E are closed in the same way as mentioned above. Then, the electric motor M 2 rotates in a reverse direction so as to change the angle of the right-hand mirror R toward the right.
  • the left-handed mirror L is controlled in the same way as described above.
