Definitions

  • This invention relates to electrical switch assemblies. It was developed primarily for those switches with a "joystick” control, but the basic principle is applicable to switches with a control element that moves in one plane only.
  • a joystick switch assembly has a lever which is directly biased by a spring into a central, neutral position. The operator can shift it away from this in any direction "around the clock", and there are usually four microswitches arranged equidistantly around the lever which are selectively operated by a formation on the lower end of the lever. Often, it is desirable only to operate one such switch at a time, but it is difficult to guard against simultaneous operation of two switches when the lever is tilted to an intermediate position.
  • an electrical switch assembly comprising a lever mounted for pivotal movement about a point and a switch spaced from the point and arranged to be operated by the lever, characterised by a slide member co-­operating with the lever and guided for movement in the place of movement of the lever, a spring-loaded element acting between the slide member and the switch to actuate the latter on movement of the lever from a neutral position and to allow de-actuation of the switch on reversion of the lever to said neutral position, the mutual co-operation of the switch and the slide member with the spring-loaded element being such that the lever when released is biased back to said neutral position by said spring loading.
  • switches there may be two switches, each with an associated spring-loaded element, on opposite sides of the pivot point, the lever being pivotable in opposite directions from said neutral position to actuate one or other of said switches through the slide member.
  • the slide members will preferably move in mutually perpendicular directions, and movement of each slide member from the neutral position can be arranged to prevent movement of the other slide member from that position. Thus only the switch or switches associated with a single slide member can be actuated at one time.
  • the lever For example, if the lever is moved in the north-­south direction, it will shift one slide member in that direction, operating a group of switches on an east-west axis. The other slide member (the east-west one) is not moved and a group of switches on the north-south axis will remain unaffected.
  • the or each spring-loaded element is a plunger urged against the associated switche by a spring reacting against the slide member.
  • the or each switch then preferably has a rocker with a detent in which the associated plunger engages to hold the rocker in a first switching position when the lever is in said neutral position.
  • the plunger shifts in relation to the detent to tip the rocker to a second switching state.
  • the lever is released the reaction from the plunger through its spring urges the associated slide member and the lever back to the neutral position, the plunger also returning to its initial position in the detent.
  • the assembly is mounted mostly within a hollow body 1 in the centre of whose top there is a bulbous, open topped guide formation 2 for a joystick lever 3.
  • This lever has an upper stem 4 to receive an operating knob 5, the lower end face of which is concave and spherically curved to match the outer face of the formation 2.
  • the lever has a part-spherical formation 6, centred on point 7, whose curved surface matches the concave inner surface of the formation 2.
  • the lever 3 can pivot about the point 7 in any direction, although of course to a limited angle. It is shown in a central, neutral position.
  • the lever 4 reduces over a conical portion 8 to a stem with an upper part 9 and a lower part 10.
  • These parts are generally square, but on each one a pair of opposite sides have part-cylindrical convex surfaces, those on the part 9 facing in directions at right angles to those on the part 10.
  • the upper slider 11 is generally rectangular in plan and shallow H-shaped in side view.
  • the central web 13 of the H has a longitudinal slot 14 in which lies the part 9.
  • this part 9 simply moves lengthwise of the slot and has no effect on the upper slider 11.
  • the convex surfaces of the part 9 engage the sides of the slot 14 and the slider 11 is shifted. It is guided by its ends 15 co-operating with the inside of the body 1.
  • the lower slider 12 is also generally rectangular in plan but U-shaped in side view, as best seen in Figure 2.
  • the web 16 of the U has a longitudinal slot 17, transverse to the slot 14, in which engages the lower part 10 of the lever 4.
  • the action is similar to that of the upper slider, with the lower one being guided by its ends 18 co-operating with the inside of the body 1.
  • each end 15 and 18 has a blind vertical bore open to the underside, and each of these receives a coil spring 19 and a plunger 20.
  • the nose of each plunger is rounded and normally rests within the apex of a V-shaped recess 21 at the centre of a rocker 22, which is the main component of an electrical switch.
  • This is mounted in a cradle 23, and on either side of the recess 21 there are extensions 24 with electrical contacts 25 on the underside.
  • the vertical section has been stepped out of the central plane to show the switch construction, and the plungers 20 and switches associated with the upper slider 11 are omitted for clarity.
