Definitions

  • a pushbutton assembly having a cap and a body member which are formed so that they have interlocking means by which they form an assembly when placed together.
  • the body and the cap each include projections which serve to keep the assembly in position in an opening through which they have been assembled.
  • This invention relates to pushbutton assemblies and switches operated by them.
  • a pushbutton assembly for operating a switch enclosed within a protective cover, through a hole in said cover, comprising a body member adapted to cooperate with such a switch and a cap arranged to fit over said body member, said cap and said body members having interlocking means for holding them in mutual contact, and in which said body and said cap are further provided with projections to retain said assembly within a hole in said cover.
  • the pushbutton assemblies With equipment such as telephonic intercommunication apparatus operated by pushbutton switches, it is advantageous if the pushbutton assemblies remain attached to the protective cover when the apparatus is removed, for example, for servicing.
  • This object can be achieved by making the pushbutton in two parts having projections which engage the edges of the hole in the cover through which the pushbutton operates its associated switch.
  • the pushbutton By making a pushbutton which is assembled in situ and the components of which are held in place by interlocking means provided on them, the pushbutton may be made to act as a holder for a card or other replaceable indicator means.
  • FIG. 1(a) shows a front view of a cap for a pushbutton assembly
  • FIG. 2(a) shows a front view of a body for the same pushbutton assembly
  • FIG. 2(b) shows a side view of the body
  • FIG. 3 shows a cross-sectional view of the assembly mounted on a switch and projecting through a hole in the protective cover for the switch;
  • FIG. 4 shows the relationship between the cap 1 and body 4 as seen in a top view of FIG. 3 and demonstrates the appearance of an exemplary digit 5 as seen through the transparent material of the cap.
  • the cap 1 consists of a transparent plastic moulding made from clear polystyrene or like material. Its upper surface 2 is covered to facilitate operation and its sides are provided with holes 3 to interlock with the body member 4.
  • the body member is moulded from Cycolac T or like material, and has rounded projections 5 to interlock with the holes 3 on the cap.
  • An internal projection 6 operates a switch by means of a push rod (not shown). Both the cap and body are provided with projections (7 and 8, respectively) which engage with the sides of the switch cover when the pushbutton is assembled and prevent the button from falling out of the case.
  • Cap 1 fits over body 4, the holes 3 on the cap interlocking with projections 5 on the body.
  • a space 9 is provided between the cap and body to act as holder for an indicator card or other indicating means which is visible through the transparent material of the cap.
  • the internal projection 6 on the body of the switch operates on push rod 10.
  • the pushbutton assembly is retained within the switch cover 11 by projections 7 and 8 on the cap and body, respectively, but may be removed by pulling the two apart.
  • a pushbutton assembly for operating a switch enclosed within a protective cover through a hole in said cover, comprising a body member adapted to cooperate with such a switch, a cap fitted over said body member, said cap and said body members having interlocking means holding them as an assembly in mutual contact, and said body and said cap each including projections to retain said assembly within a hole in said cover.
  • a pushbutton assembly substantially as claimed in claim 1, in which the interlocking means includes a projection on the cap engaging a hole on the body member.
  • a pushbutton assembly substantially as claimed in claim 1 in which said cap is made of transparent material and indicating means provided within the assembly is visible through the cap.
