Definitions

  • This invention relates to a relative thin-type sliding operation type switch apparatus in which a switched-off state is changed over to a switched-on state (or from the switched-on state to the switched-off state) when a click touch is produced by sliding the operation knob, and when the operating force is removed, the operating knob is automatically returned back to its initial position.
  • a switch comprised of a moving member (a sliding member) having an operating knob and a sliding element fixed to it; a case for storing this moving member in such way that the moving member can be slidably moved; a printed circuit board having some contact patterns moved to or away from the sliding member; and a coil spring for automatically returning the moving member to its initial position, and then a click mechanism is constituted by a protrusion arranged at a side surface of the moving member and another protrusion arranged at an inner side surface of the case.
  • the click mechanism is operated such that the protrusion of the moving member is engaged with or disengaged from the protrusion of the case, wherein the engaged relation between the two members is utilized, so that considering a disturbance in size (tolerance) generated at the forming stage or assembling stage shows that it is difficult to define strictly a timing where the click touch is produced.
  • the sliding operation type switch in which the timing where the click touch is generated and the timing where the switched-on or switched-off state is changed over are substantially displaced provides a poor convenience in use for an operator.
  • the present invention is operated such that as the moving member is slid by a predetermined amount, a driving member is driven in a direction opposite to its moving direction to depress a tact spring and as this tact spring is reversed, the switched-on or switched-off change-over state of the switch is carried out along with a production of this click touch.
  • a sliding operation type switch as described above is operated such that a presence of the driving member causes an operating force for slidably moving the moving member to be changed to a force for depressing and operating the tact spring and then as one member of this tact spring is reversed in operation, a production of the click touch and the changing-over of the switched-on or switched-off state are carried out substantially in a synchronous manner.
  • the sliding operation type switch apparatus constituted as described above is operated such that as the operating knob exposed out of the opening of the case is operated to cause the moving member to be slid by a predetermined amount against a resilient force of the recovering means, this moving member drives the driving member in a direction intersecting its moving direction and the driving member pushes the tact spring with the driving force, so that the switched-on state or switched-off state of the switching section can be changed over by the reversed tact spring.
  • the sliding operation type switch apparatus is operated such that the operating force for moving the moving member is changed over to a force for depressing and operating the tact spring through the driving member and at same time a click touch is produced as the reversing operation of the tact spring is carried out and the switched-on or switched-off state at the switching section are changed over.
  • the click touch is produced at the time when the tact spring is reversed and the switched-on or switched-off state is changed over just after reversing operation. Accordingly, there occurs no possibility that a timing where the click touch is produced and another timing where the switched-on or switched-off state of the switching section is changed over are displaced undesirably.
  • the driving member is operated to turn and the tact spring is depressed by it.
  • the driving member is provided with a fulcrum point acting as a center of turning operation and an acting portion positioned more near to the moving member than that of fulcrum point, wherein the moving member is engaged with the acting portion when the moving member is slid and moved, the driving member is rotationally driven around the fulcrum point, the driving member may be operated smoothly and positively by the moving member during its sliding motion.
  • the driving member is provided with a position setting hole and a restricting member inserted into the position setting hole is protruded at the case, the positional displacement of the fulcrum portion is prevented by the restricting member when the driving member is turned, resulting in that it is possible to stabilize a lotus of the acting portion and to perform a positive depression of the central part of the tact spring and further it becomes possible to improve more a reliability in operation.
  • a leaf spring as the returning means
  • a coil spring as the returning means.
  • the end part of the coil spring is restricted in its position by the driving protrusion during sliding motion of the moving member and compressed, a self-return mechanism is simplified and a small-sized thin formation of an entire switch may easily be promoted.
  • the tact spring has a function to generate at least a click touch.
  • the tact spring has a function for generating a click touch and another function for acting as a movable contact point.
  • the fixed contact point is arranged on the board as the switching part, it is possible to change over the switched-on or switched-off state of the switching section as the tact spring is reversed, so that the number of component parts can be reduced.
  • the sliding operation type switch shown in these figures is mainly comprised of a moving member 1 having an operating knob 2 or a spring storing part 3; a case 5 having an opening 4 for exposing the operating knob 2 and storing the moving member 1 in such a way that the moving member can be slid and moved toward a predetermined direction (the right and left direction in Figs.1 to 4); a coil spring 6 arranged within the spring storing part 3 of the moving member 1 while its extending or retracting direction is being substantially coincided with the predetermined direction; a supporting plate 7 integrally formed at the lower end of the case 5; a flexible board (substrate) 8 fixed on the supporting plate 7 and having a contact pattern (a fixed contact point) not shown; a tact spring 9 mounted on the flexible board 8 to cover the contact pattern and generating a click touch when it is turned in a reverse direction; an adhesive tape 10 fixing the tact spring 9 to the flexible board 8; and a driving member 11 (refer to Figs.7 and 8) connecting a fulc
  • a tapered part 1a opposing to the acting part 13 of the driving member 11 is formed at the extremity end of the moving member 1 sliding along it, both ends of the spring storing part 3 become receiving portions 1b of the coil spring 6 under no load and then one of the receiving portions 1b is provided with a recess 1c for use in inserting a driving protrusion 5a to be described later.
  • a driving protrusion 5a inserted into the recess 1c and abutted against one end of the coil spring 6, and a restricting part 5b inserted into a position setting hole 11a arranged between the fulcrum point 12 and the acting part 13 of the driving member 11.
  • This driving protrusion 5a is extended toward a sliding movement direction of the moving member 1 to guide the recess 1c when the moving member 1 is slid and moved and to restrict a position of the coil spring 6 for compression.
  • the restricting part 5b restricts a position of the entire driving member 11 to prevent a positional displacement of the fulcrum point 12 when the driving member 11 rotates.
  • the tact spring 9 may also act as a movable contact point and this spring can be moved to or away from the contact point pattern (the fixed contact point) on the flexible board 8.
  • the acting part 13 of the driving member 11 is provided with a pressing protrusion 13a abutted against the central part of the tact spring 9. When the central part of the tact spring 9 is pushed by the pressing protrusion 13a and oppositely turned, a click touch is generated and concurrently the tact contact spring 9 comes into contact with the fixed contact point to be changed from the switched-off state to the switched-on state.
  • the driving means 11 is rotationally driven around the fulcrum point 12 due to the fact that when the tapered part 1a is engaged with the acting part 13 as the moving member 1 is slid, the acting part 13 is pushed down by the tapered part 1a.
  • the moving member 1 is moved from the position shown in Figs.3 and 4 toward a leftward direction by the resilient force of the coil spring 6 of which position is restricted by the driving protrusion 5a and compressing amount is increased and then the moving member is automatically returned back to the initial position shown in Figs.1 and 2, resulting in that the moving member 1 is returned automatically to the original switched-off state.
  • the sliding operation type switch of the preferred embodiment is operated such that the operating force for slidably moving the moving member 1 is converted to a force for pressing the tact spring 9 through the driving member 11, the click touch is generated when the tact spring 9 is oppositely turned, and then the switched-on state or switched-off state is changed over. Accordingly, there occurs no possibility that a timing where the click touch is produced and a switch-over timing of the switched-on or switched-off state of the switch are displaced undesirably, resulting in that an erroneous operation can be prevented positively and its convenience in use is also improved.
  • the tapered part 1a of the moving member 1 is engaged with the acting part 13, thereby the driving member 11 is rotationally driven around the fulcrum point 12 and a positional displacement of the fulcrum point 12 during the turning operation is prevented by the restricting part 5b arranged at the case 5, resulting in that the driving member 11 can be operated smoothly and positively by the driving member 1 when it is slid.
  • a driving member in which the sliding motion of the moving member 1 can be converted into an operation (for example, an upward or downward motion) other than rotation.
  • the driving protrusion 5a for use in compressing the coil spring 6 is extended in a slide moving direction of the moving member 1 and at the same time its partial portion is inserted into the recess 1c even in both cases of non-operated state (under no load state) and of operated state, resulting in that the driving protrusion 5a is not engaged with the recess 1c and the moving member 1 can be slid and moved smoothly.
  • the operating knob 2 is integrally formed with the moving member 1, it is also applicable that both members are separately arranged and the operating knob 2 is fixed to the moving member 1. Similarly, it is also applicable that the top surface (an upper wall) and the side surfaces (side walls) are formed as separate component parts.
  • the tact spring 9 is also applied as a movable contact point in the preferred embodiment, it is also available that the movable contact point is arranged in separate from the tact spring 9 in such a way that a membrane switch is used in place of the flexible board 8 and then the tact spring 9 is mounted on the membrane switch. Additionally, if a rigid board is used in place of the flexible board 8, the rigid board may have a function of the supporting plate 7.
  • a sliding member is arranged at the lower surface of the moving member 1 and some conductive patterns such as resistors or electrical collectors which are in slidable contact with the sliding member are arranged at the flexible board 8, it is also possible perform simultaneously a changing of resistance value accompanied by the sliding motion of the moving member 1 in separate from the aforesaid switching mechanism where the driving member 11 or the tact spring 9 is present.
  • the click touch is generated by the opposite turning action of the tact spring and at the same time the switched-on state or switched-off state is changed over, even if the size disturbance in each of the component parts or disturbed state in assembly occurs, a timing where the click touch is produced and another timing where the switched-on or switched-off state is changed over can always be coincided to each other, an erroneous operation can be prevented and a convenience in operation can be improved and at the same time the operating stroke can be easily reduced, resulting in that a degree of freedom in design is also expanded.
