Definitions

  • switches which are operated by doors are frequently plagued by maladjustments because of discrepancies in the tolerances between the door and the frame on which the switch is mounted.
  • a number of switches are available in the prior art which allow some adjustment when the door is closed. Most frequently, these switches have a plunger which is movable within an adapter in the switch body having means of holding the plunger in place after the adjustment has been made.
  • spring elements have been mounted within the switch housing projecting beyond the area of the housing, engageable with the edge of the application hole and adapted to flex inwardly and assure a tight fit.
  • the prior art also discloses a panel light which has flexible wraparound fins as interference means projecting from a tubular plastic carrier.
  • There is also prior art which utilizes rather short fins engageable on the opposite side of an apertured panel and cooperatively hold the switch with a rib which is parallel to the engagement surface of the fins and spaced therefrom.
  • This invention is directed at an adjustable switch housing for use as a door switch.
  • the housing has a series of flexible louvers which extend for the major portion of the length of the housing on planes which are parallel to the axis of the housing.
  • the diameterdefined by the edges of the louvers is greater than the diameter of the application hole with which the housing is to be engaged.
  • FIG. 1 is a front elevation of a switch showing the novel housing
  • FIG. 2 is a rear elevation of the switch shown in FIG. 1;
  • FIG. 3 is a section taken on line 3-3 of FIG. 1;
  • FIG. 4 is an elevation of the switch shown in FIG. 1 with the plunger depressed
  • FIG. 5 is a side elevation of the plunger of the switch shown in FIG. 1;'and
  • FIG. 6 is a front elevation of a variation of the switch shown in FIG. 1.
  • This invention comprises a switch housing 10 generally tu bular in construction and having a series of axial louvers 12 extending from the body of the switch housing 10, tapering as a leadin toward the forward portion thereof and toward the rear portion, if desired.
  • the angle of a louver 12 to the housing 10 may be varied to increase or decrease the interference with the edge of an application hole.
  • the housing 10 may contain switch elements such as a plunger 14 having a head portion 16, a median portion 18 and a shank portion 20 which extends from the median portion 18 and which forms a shoulder therewith.
  • the shank portion 20 is circumscribed by a helical compression spring 22.
  • This assembly is placed within the housing 10 so that the spring 22 is trapped between the slope formed at the forward end of the housing 10 and the shoulder provided by the median portion 18 and the shank portion 20.
  • the shank portion 20 is then passed through an aperture formed in the forward end of the housing I0 and is there fixedly engaged with a contact element 24 which butts against the external surface of the housing 10 and makes electrical contact therewith.
  • the contact 24 is moved away from the housin It) opening the circuit.
  • the housing I0 is manually pushed part way into the aperture and the door stile is then slammed against the plunger 14 of the switch driving the housing 10 into the aperture while allowing it to protrude the proper distance beyond the support for efficient operation.
  • the circles defined by the highest portion of the length of the edges of the louvers 12 are slightly greater than the diameter of the aperture thereby assuring a firm interference fit.
  • the louvers 12 will flex inwardly as the housing is driven in providing proper interference even though there may be variations along the edge of the aperture.
  • FIG. 6 A variation of the housing disclosed in FIGS. I through 4 is shown in FIG. 6.
  • the housing variation 10a comprises a tubular body portion open at both ends and tapering from the first opening 26 at one end to a smaller diameter second opening 28 at the other end.
  • a longitudinal slot 30 is formed extending from the first opening 26 to the second opening 28.
  • An electrical switch comprising a plunger movably associated within a tubular housing which is open at both ends, the plunger comprising a head portion, a leg extending from the head portion and having a diameter less than the head portion, the head extending beyond the housing on one side and the leg extending beyond the housing on the opposite side, a spring associated with the head portion and with a surface of the housing adjacent the end opposite the head portion and the leg portion attached to a contact element which is engaged with the housing, the housing having several flexible louvers extending outwardly therefrom along the length thereof and having first side edges the major portion of which lie on a plane parallel with the axis of the housing each of said louvers having both ends and the second side edge fixed in position and having the first side edge free.
  • leg has a median portion extending from the head portion and having a diameter less than the head portion, a shank portion integral with the median portion and of less diameter than the median portion, the shank portion being the part of the leg extending beyond the housing on one side and the spring circumscribing the median portion.
