Definitions

  • a lever switch comprises (a) converter means rotatably supported in a switch receptacle for rocking left-andright and converting a movable contact plate relative to a stationary contact or contacts, and (b) a lever for actuating said converter means which is formed separately from said converter means.
  • Said lever and said converter means are connected with each other by engaging the upper surface portion of a lug, provided at a lower portion of the inner surface of said lever, with a corresponding surface portion of said converter means so that when the assembly of said lever and said converter means is at the neutral position relative to the switch receptacle said lever can be detached resiliently from said converter means, whereas when the assembly is at either of the rocked end positions said lever cannot be detached from said converter means, by reason of the fact that alower portion of the outer surface of said lever contacts with the inner wall surface of the receptacle at the same time when the inner lug of said lever engages a corresponding portion of said converter means.
  • the novel switch comprises (a) a converter means rotatably supported in a switch receptacle for rocking left-and-right and converting a movable contacl plate relative to a stationary contact or contacts, and (b) a lever for actuating said converter means which is formed separately from said converter means.
  • Said lever and said converter means are connected with each other by engaging the upper surface portion of a lug, provided at a lower portion of the inner surface of said lever, with a corresponding surface portion of said converter means so that when the assembly of said lever and said converter means is at the neutral position relative to the switch receptacle said lever can be detached resiliently from said converter means, whereas when the assembly is at either of the rocked end positions said lever cannot be detached from said converter means, by reason of the fact that a lower portion of the outer surface of said lever contacts with the inner wall surface of the receptacle at the same time when the inner lug of said lever engages a corresponding portion of said converter means.
  • FIG. 1 is a side elevational view of a switch according to the invention
  • FIG. 2 (a) and FIG. 2 (b) are its decomposed perspective views
  • FIG. 3 is a partial side view showing an undesirable condition of engagement
  • FIG. 4 is a partial side view showing a desirable condition of engagement.
  • the invention relates to the construction of a lever switch in which a lever as an operating member of the switch is mounted detachable, while it is never detached at the end positions of operation in normal use.
  • 1 is a base member of the switch and 2 is a cover member, which both members constitute a receptacle of the switch.
  • the cover 2 has attached thereto at its left and right hand side surfaces spring plates 3 which are utilized when the switch is mounted in a hole of a panel and the like.
  • 4 is a lever as an operating member of the switch
  • 5 is a converting member for actuating the switching conversion of contacts of the switch, which both members are formed originally separated from each other as shown in FIG. 2 (a) and (b) respectively.
  • the lever 4 is formed hollow with an upwardly projecting portion for operating said switch, as seen from the section view shown in FIG. 1, and has projections 6 formed downwards at the lower ends of its left and right hand side walls as shown in FIG. 2 (a). Further, each of projections 6 has a lug 7 formed on its inner surface and a downwardly extending extension below the lug 7.
  • the lever 4 is made of sucha material that its lower projections 6 have proper resilient flexibility.
  • the converter 5 has a configuration such as that shown in FIG. 2 (b), in which frame members 9 are attached to front and rear sides of a box 8, and these members 8 and 9 are formed continuously as one body.
  • the converter 5 is provided on its front and rear side surfaces at their upper portions with shafts or shaft-like projections 10 which are fixedly or loosely mounted thereto, and the converter is mounted rotatably to cover 2 by inserting the projectons 10 into recesses formed on the front and rear side walls of cover 2.
  • the lever 4 is connected to converter 5 by fitting the former slidingly to the latter so that inner surface lugs 7 of lower projections 6 of the lever will enter into the lower surface of square box 8 of the latter.
  • the connecting operation and the removal operation are performed by utilizing the resiliency or elasticity of projections 6.
  • the lever 4 is usually made of transparent or at least semi-transparent colored synthetic resin, and in order to illuminate it from its interior, a lamp 11 is mounted at the inner base portion of square box 8 of converter 5. At the center portion of lower surface of each of front and rear frame portions 9 there is provided a recess within which a sliding member 13 (see FIG. 2 (b) is inserted with a spring 12 (see FIG. 1).
  • the insulator base member 1 has penetrated therethrough and secured thereto a central terminal 14 and left and right terminals 15 and 16, respectively, and a movable contact plate 17 is placed on the top end of the central terminal 14 free to incline to the left and to the right.
  • the upper surface of each of terminals 15 and 16 forms a stationary contact against the movable contact 17.
  • the lower end of sliding member 13 is placed on the upper surface of movable contact plate 17 under pressure; it may be shifted left and right by the rocking operation of lever 4 to convert the on and of states of the left and right hand side contacts.
  • lever 4 and converter 5 are thus constructed removably as above stated, it might happen sometimes that at the end of an operation oflever 4, for converting its inclined state from either one side to the other side, one side portion of lever 4 would be disengaged from converter 5 to float up and eventually be separated entirely. The reason is that such a situation as shown in FIG. 3 would occur. That is to say, in FIG.
  • lever 4 being made removable or detachable is that it becomes easily possible to select any one color of the lever which serves as indicator of on or of state of the switch from various possible colors, for example, red, blue, yellow and others; or, to change the color one to another, in accordance with customers demands. Namely, the necessity as before to prepare beforehand a large number of switches per each of those various colors is eliminated, and it is only necessary to prepare switch main parts except lever 4 as common for all and only levers 4 of various different colors, thereby various demands of customers can be met immediately, with the result that the amount of goods in stock can be considerably reduced.
  • lever 4 the removal or exchange of lever 4 as described above can be easily performed, while in normal use condition the lever 4 is prevented from detachment from converter 5, being connected thereto even against impulsive force produced at the end of left and right rocking operation of lever 4.
  • a lever switch comprising a receptacle
  • converter means rotatably supported in said receptacle for rocking to the left and right and converting said movable contact member relative to said stationary contact;
  • each projection having means on its inner surface for resiliently engaging the outer surface of said converter means, the lower end of the outer surface of said projections being spaced from the inner wall of said receptacle when said lever is in the central neutral position, said space being sufficient to permit said projections to be resiliently disengaged from said converter wall, and when said lever has been rocked to the left or right position said projections move to substantially close said space so that said space is insufficient to permit such disengagement.
  • a lever switch according to claim 1 wherein the left and right lower ends of said lever are positioned lower than the rotation center shaft of said lever.
  • a lever switch as claimed in claim 1 wherein said means on the inner surface of each projection for resiliently engaging the outer surface of said converter means comprises a lug.
