  • a switch of the foregoing type is advantageous in that a single mechanism can be used, which mechanism can be placed in either of two operating modes.
  • alternate operation is provided by a mechanism that can be toggled or snapped over-center upon depression of a push-button.
  • momentary operation is provided in that the mechanism is biased to one position only. When the mechanism is shifted to the other position by the push-button, the mechanism stays in that position only so long as the push-button is held.
  • An object of this invention is to provide a switch of the foregoing type in which the operating mode, namely alternate action or momentary action, can be changed by simply shifting the position of a lever that forms part of the switch contact actuating mechanism whereby the lever serves to latch the mechanism in the alternate action mode but is unlatched from the mechanism in the momentary action mode and tends to bias the mechanism to only one position.
  • a further object of this invention is to provide a switch that has a push button operated carrier that integrally includes a pawl for operation of a ratchet that forms part of the switch mechanism, the pawl being integrally connected to the carrier by spaced bridges of material that form torsion spring connections, whereby the pawl rotates about an axis passing through those bridges when the pawl engages the ratchet for operation of the same.
  • a still further object of this invention is to provide a switch of the type and for the purpose stated in which a lamp is housed within the push button, and wherein the lamp is adapted to remain illuminated when the push button is either in its actuated or non-actuated position.
  • the switch comprises a housing with at least one fixed switch contact and at least one movable switch contact; however, in the form of the invention to be described there are four fixed and two movable contacts to provide two simultaneously operable double-pole, double-throw switches.
  • a contact-actuating mechanism includes a ratchet rotatable in the housing and having a camming surface adapted to bear against the movable contact or contacts.
  • a carrier is in the housing and has a pawl movable toward and away from the ratchet, the pawl being preferably T-shaped and being joined to said carrier by bridges of material that form torsion springs.
  • a spring-biased lever in the housing is mounted in one operative position at which it is pivotally supported by spaced trunions.
  • the lever has a latching nose for engagement with the ratchet at notched regions of the ratchet to latch the ratchet in either of two selected positions to which the ratchet may be shifted by a toggle action.
  • the housing has an opening for access to the lever and by which the lever may be shifted to a second position of pivotal support on the trunions so that the latching nose of the lever may then engage the ratchet at other regions and in a non-latched condition. In this non-latched condition the lever biases the ratchet toward only one position, this bias being overcome only so long as the push button is depressed to rotate the ratchet to another position.
  • FIG. 1 is a perspective view of a switch constructed in accordance with and embodying the present invention
  • FIG. 2 is a fragmentary sectional view, on an enlarged scale, taken along line 22 of FIG. 1;
  • FIG. 3 is a fragmentary perspective view of the carrier that forms part of the present invention and being shown with the lamp bulb terminals assembled therewith;
  • FIG. 4 is a fragmentary sectional view taken approximately along line 4l4 of FIG. 2;
  • FIG. 5 is an exploded perspective view of the base assembly and associated mechanism that forms part of the switch and with certain parts broken away for purposes of clarity;
  • FIG. 6 is a fragmentary sectional view of a part of the structure in FIG. 2 but on an enlarged scale and showing the mechanism set for operation in the alternate action mode and being in one of two positions thereof;
  • FIG. 7 is a view similar to FIG. 6 and showing the other position of the alternate action mode
  • FIG. 8 is a sectional view similar to FIGS. 6 and 7 but showing the mechanism set for operation in the momentary action mode and with the push button and pawl retracted from the ratchet;
  • FIG. 9 is a sectional view similar to FIG. 8 and showing the pawl engaging the ratchet as would be the case in the momentary action mode when the push button is depressed.
  • a switch 2 having a housing 4 that includes at its lower end a base 6.
  • the base 6 is of generally rectangular configuration and has an upstanding ledge 8 that telescopes within the open bottom of the housing 4.
  • the housing 4 and base 6 are each formed of a suitable plastic material, and the two may be secured together in any suitable manner.
  • the housing 4 is of generally rectangular cross section but at its upper end there is a cylindrical stem 10.
  • the stem 10 has an external thread for receiving a nut (not shown) so that the switch housing 4 may be mounted on a panel or the like.
  • terminals 12a, 14a, 16a adjacent to one edge of the base are three terminals l2, l4, l6, and adjacent to the opposite edge of the base are similar terminals 12a, 14a, 16a.
  • Each group of terminals provides a single-pole, double-throw switch.
  • Terminal 16 is bent at one end to provide a fixed switch contact 18 while terminal 14 is bent at one end to provide another fixed switch contact 20.
  • Terminal 12 carries a spring blade that serves as a movable contact 22 and which is actuated by mechanism hereinafter more fully described.
  • Corresponding contacts are present on the terminals 12a, Ma, 16a.
  • the lamp terminal 24, 26 are connected to a lamp power supply for purposes presently more fully appearing.
  • a push button 28 mounted for reciprocation within the upper end of the housing 4 is a push button 28 that includes a plunger 30 and a cap 32, the plunger 30 extending through the opening 34 in the upper end of the stem 10.
  • the plunger 30 is formed with opposed longitudinal slots 36, 38, the slot 36 having a detent 40 near its upper end.
  • the detent 40 is adapted to engage a shoulder 42 in the stem to retain the push button 28 assembled with the housing.
  • shank of the plunger 30 will, by reason of the presence of the slots 36, 38, be capable of being radially 60 to permit the leading tapered end of the plunger to be inserted into the 13 34 after which the plunger will resiliently expand to provide the radial overlap between the detent 40 and the shoulder 42.
  • a conventional lamp bulb 44 having contacts 46, 48 which are in series with the filament within the lamp bulb.
  • a resilient secondary lamp terminal 50 projects through the slot 38 and engages the annular lamp contact 46.
  • An additional resilient secondary lamp terminal 52 of generally L-shape engages the central or axial lamp contact 48.
  • the lower ends of the terminals 50, 52 are in abutting engagement with push button return springs 54, 56, the return springs 54, 56 also receiving and being in abutting contact with the lamp terminals 24, 26. Electrical continuity is maintained through the springs 54, 56 to the lamp bulb 44 regardless of whether or not the push button 28 is in its depressed or released position so that the lamp bulb 44 will remain on as long as power is supplied to the terminals 24, 26.
  • a molded plastic carrier 58 that is of generally rectangular shape having a central downwardly opening cavity 60 (FIG. 4).
  • the carrier 58 has opposed side walls 62, 64 each of which has a slot 66 for receiving one of the return springs 54, 56.
  • the upper end of the slot 66 terminates in a widened part 68 that receives the terminal 50 and wherein the terminal bears against abutments 70.
  • a thinned out tongue 72 of the terminal telescopes within the return spring.
  • the top wall of the carrier 58 also has a slot 74 for receiving the terminal 50 whereby the terminal 50 is anchored in the carrier 58.
  • the side wall 64 and the adjacent part of the top wall of the carrier is similarly constructed for receiving and retaining the terminal 52, and therefore includes a slot 74 (FIG. 3) in the top wall of the carrier and a widened part 68' (FIG. 2) for receiving the lower portion of the terminal 52.
  • the other pair of opposed side walls 76, 78 of the carrier are formed with vertical slots 80, 80 that are received in ribs 82, 82 that project inwardly from two opposed walls of the housing 4.
  • This provides, in effect, a pair of opposed rails for guiding the reciprocating movement of the carrier 58 which, as will now be apparent, is movable with the push button 28 in opposition to the return springs 54, 56.
  • a pawl 84 which is joined to the top wall by spaced bridges 86, 86 (FIG. 4) of the plastic material of the carrier. These spaced bridges 86, 86 are effectively provided by reducing the thickness of the top wall as shown by the arcuate recesses 88 appearing in FIG. 4.
  • the wall 83 is formed with slots 90, 90 (FIG. 3) on opposite sides of the pawl 84 and extending between the bridges 86, 86.
  • the pawl 84 as viewed in FIG. 4, is a generally T-shaped element with the ends of the T being joined to the carrier by the spaced bridges 86, 86.
  • bridges define torsion bars to provide a torsion spring connection between the pawl 84 and the carrier.
  • the pawl When force is applied to the pawl 84 tending to bend it left or right (FIG. 2) the pawl will not be significantly bent transversely. On the contrary, the pawl will remain substantially straight as seen by the broken line position of the pawl in FIG. 2. However, the pawl will pivot about the axis 92 in opposition to the torsion springs formed by the bridges 86, 86, and for purposes presently more fully appearing.
  • ratchet 98 rotates on the journal pin 96 for movement about the pin axis 100.
  • the ratchet 98 has a central portion that lies between the trunions 94, 94. This central portion has converging surfaces 102, 104 and spaced apart ratchet teeth 106, 108. Laterally outwardly of the trunions 94, 94 the ratchet 98 has camming surfaces 110, for respective engagement with the movable contacts 22, 22.
  • the movable contacts 22, 22 are, as a result of their normal spring bias, in engagement with the contacts 18, 18 when the ratchet 98 is in the position shown in FIGS. 2, 6 and 8, and in which position the camming surfaces 110 are slightly spaced from the movable contacts 22, 22.
  • the camming surfaces 110 depress the movable contacts 22, 22 causing them to engage their respective contacts 20, 20.
  • the latching lever 112 rigidly receives a pin 114 that extends laterally of the latching lever 112 for pivotal disposition in the trunions 94, 94.
  • the trunions 94, 94 have, as best seen in FIG. 5, two pairs of aligned notches 116, 116 and 118, 118.
  • the pin 114 is sized for rotatable seating selectively in either the notches 116, 116 or the notches 118, 118 for pivotally supporting the lever about spaced parallel axes, one axis being for each operative position.
  • a downwardly opening annular recess 122 Adjacent to the forward end 120 of the lever 112 is a downwardly opening annular recess 122 for retentively receiving the end portion of a coil spring 124.
  • the coil spring 124 also bears against the inside surface of the base 6 and tends to bias the latching lever 112 for clockwise rotation (as illustrated herein) about the axis of the pivot pin 114 whether the latter is in the notches 116, 116 or in the notches 118, 118.
  • the base 6 has an elongated access opening or slot 126 for receiving a small diameter pin, wire, or other small tool.
  • This tool can be inserted into a blind hole 128 in the bottom of the lever 112 for manipulation of the lever 112.
  • the lever can be lifted so that the pin 114 is removed from the notches 116 as in FIGS. 6 and 7, and shifted by the tool to the left for seating in the notches 118, 118, as shown in FIGS. 8 and 9.
  • the reverse procedure may be carried out in a like manner, and in each instance the lever is shifted with the coil spring 124.
  • the pin 114 is readily reseated in the pair of notches to which it is shifted because the force of the lever 112 against the ratchet due to the spring 124 tends to urge the pin 124 downwardly toward the notches 116, or 118, as the case may be.
  • the lever 112 has an upwardly presented, generally triangular latching nose 130 for engagement with the underside of the ratchet at predetermined regions depending upon whether or not the lever is in the notches 116 or the notches 118. This, in turn, determines whether or not the switch is in the alternate action mode or in the momentary action mode.
  • FIGS. 6 and 7 show the mechanism in the alternate action mode, and in this mode the lever pin 114 is in the notches 116, 116.
  • the central part of the ratchet has two spaced apart latching notches 132, 134 for engagement by the latching nose 130 in either of two positions in which the ratchet has been shifted by a toggle action. Thus, in FIG. 6 where the ratchet is in one position the latching nose 130 engages the notch 132; in the other position the latching nose 130 engages the notch 134.
  • the lever 112 If, however, the lever 112 is shifted so as to be seated in the notches 118, 118, as shown in FIGS. 8 and 9, the lever 112 will be in a position such that the switch mechanism is in the momentary action mode. In such case one surface of the latching nose 130 will bear against an intermediate surface 136 (FIG. 8) on the ratchet that is located between the notches 132, 134. As the ratchet 98 moves from the position shown in FIG. 8 to that shown in FIG. 9, the pointed end of the latching nose 130 initially engage the notch 134 and then engages the bottom surface portion 138 of the ratchet beyond the notch 134.
  • the latching nose 130 When the ratchet has rotated past dead center, the latching nose 130 will then be past the dead center apex 140 of the ratchet. Therefore, the spring 124 will cause the latching nose 130 to apply force to the ratchet along a line to the right (FIGS. 6 and 7) of the axis 100. This causes the ratchet to snap into the position shown in FIG. 7 and with the latching nose 130 now locking the ratchet by reason of engagement in the latching notch 134. The ratchet remains in the position shown in FIG. 7 after the push button is retracted. To shift the ratchet from the position shown in FIG. 7 back to the position shown in FIG.
  • the push button is depressed causing the pawl 84 to deflect as shown in broken lines (see FIG. 2) and engage the ratchet tooth 108.
  • the ratchet is then toggled over center causing the latching nose 130 to apply force to the ratchet along a line to the left of the axis 100.
  • the latching nose 130 then snaps into the latching notch 132 to lockthe ratchet in position.
  • the pawl 84 engages the surface 102 and ratchet tooth 106 each time the push button 28 is depressed. This always rotates the ratchet counterclockwise to move it to the position shown in FIG. 9. However, the line of force applied by the spring biased latching nose 130 is always to the left of the axis causing the ratchet to be biased in a counterclockwise direction. Thus, when the push button 28 is released, this counterbiasing of the spring 124 returns the ratchet to the position shown in FIG. 8.
