  • the rotor member includes a central body portion having fixed thereto and formed integrally therewith a resiliently deformable beam member which carries a detent. As the rotor is actuated, the beam deforms as it leaves one switch position and then the 'beam applies a pressure causing the detent to snap into place between a pair of registration posts positioned within the cavity thereby positively indexing the switch at a predetermined switching position.
  • a contact element carried by the rotor member which contact element while in a switch position or station completes an electrical circuit between a stationary contact element and a common electrically conductive collector element.
  • a plurality of contact actuation members Positioned between the stationary contact element and the common collector is a plurality of contact actuation members which bear against the contact element during its rotational movement.
  • a housing 11 includes a cover 12 affixed to a base member 13 which includes an upstanding side wall 14.
  • the interior portion of the cover 12 is coated with a sealing means such as, for example, a silicone rubber liner 15.
  • the rubber liner 15 terminates at its inner end in a sealing gland 16 and extends around the upstanding side wall 14 of the base 13 and operates as a seal between the cover 12 and the lower portion of the base member 13 when the cover 12 is crimped into place.
  • An opening is provided in the upper portion of the cover member 12 through which a rotor actuating means such as shaft 17 protrudes as is well known in the prior art.
  • a movable contact member 22 is aflixed to a rotor member 23 which is actuatable by the shaft 17 and causes a movable contact 22 to break and make electrical continuity with the stationary contact 19.
  • Actuation of the movable contact 22 to positively cause the make and break of the electrical continuity is generated by a plurality of cams such as that shown at 23 which are positioned peripherally about the base member 13 adjacent to stationary contact elements 19. It should be noted that the cams 23 are positioned between the stationary contact element 19 and a common collector member 24.
  • the movable contact element 22 bridges between the stationary contact element at the particular switching station occupied by the movable contact element and the common collector 24.
  • the rotor 23 has a central body portion 26 upon which the movable contact member 22 is carried.
  • a resiliently deformable beam 27 is formed integrally with the central body portion 26 of the rotor and carries with it a detent member 28.
  • the central portion 26 of the rotor23- has a central relief 31 which receives a centrally disposed mounting post 32 extending upwardly from the base 13 of the housing.
  • the mounting post 32 may be integrally formed with the common collector member 25 which may also be integrally formed with an electrically conductive pin member 33 extending outwardly from the housing to thus form a common electrical return for the switch.
  • the rotor 23 has provided in the upper surface thereof an annular depression 34 Within which the sealing gland 16 is seated to thereby effect a positive seal of contaminants. from the interior operating parts of the switch.
  • the rotor 26 also has formed as an integral part thereof a stop member 35 which functions in the well known manner by engaging a stop base 36 formed integrally with the upstanding wall 14 of the base member 13.
  • a resiliently deformable beam member 37 is also affixed and formed integrally with the central body portion 26 of the rotor 23-.
  • a detent member 38 extends outwardly from the resiliently deformable beam 37 and engages a cam 41 which is also formed integrally with the upstanding side wall 14 of the base 13.
  • the switch actuating cams such as illustrated at 24 and 42 are also molded integrally with the base member 13.
  • the movable contact member 22 is shown in an openable position whereby electrical continuity is established between an electrical pin member 43 and the common pin 33. This electrical continuity is established by having the left side of the contact element 22 (as shown in FIG. 2) in electrical contact with the stationary contact member 44 which is connected to the electrical pin 43. The right side of the movable contact member 22 is in contact with the common collector member 25. The intermediate position of the movable contact member 22 then rests between a pair of cam surfaces such as the the ones illustrated at 24 and 42. As the rotor 23 is then actuated, for example, by placing a screwdriver or similar adjusting tool in the slot 20 as shown in FIG.
  • the intermediate portion above described of the movable contact element engages the inclined surface of the cam 24 and as the rotor is turned further, for example, in a clockwise direction as viewed in FIG. 2, the intermediate portion of the movable contact member 22 is caused to ride upwardly along the inclined surface thus causing the electrical continuity between the left side of the contact 22 and the stationary contact member 44 to be broken.
  • the contact element traverses further and is at the top of the cam 24 it occupies the position as shown in dotted lines in FIG. 2. As is illustrated in this position the left side of the electrical contact member as shown in FIG. 2, is higher than the right side thereof.
  • the side wall 14 of the base 13 has formed integrally therewith a plurality of inwardly directed detent cam surfaces such as those illustrated at 51 through 60.
  • a plurality of inwardly directed detent cam surfaces such as those illustrated at 51 through 60.
  • 10 such cam surfaces are illustrated in FIG. 3, it should be expressly understood that any given number may be formed depending upon the particular application to which the switch may be put.
  • the structure as illustrated in FIG. 3 would be utilized.
  • Such structure may, of course, be changed in the event that a double pole multi-position or triple pole multi-position switch is desired. Such a structure will become more clearly apparent when the rotor structure is more fully described hereinbelow.
  • the rotor 23 includes the central portion 26 thereof and the resiliently deformable beams 27 and 37.
  • the beam 27 carries a detent member 28 while the beam 37 carries a similar detent member 38.
  • the beams and the detents are formed integrally with the rotor 23.
  • the entire rotor structure including the beams and detents are molded as a single unit from a plastic material which has been impregnated with fiberglass. Although various plastic materials may be utilized in accordance with the presently preferred embodiment a nylon material is most desirable.
  • the beam is fixed at each end thereof such as at 62 and 63 to the central body portion 26 of the rotor 23.
  • the central body portion 26 of the rotor 23 has a smaller diameter in the area of the beam 37, such as is illustrated by the surface 64 thereof.
  • a slot 65 between the central body portion andthe resiliently deformable beam 38.
  • the slot 65 provides space within which the beam can move as the rotor is rotated. For example, assuming that the rotor occupies the position illustrated in FIG. 3 and it is desirable to change the switch position and that a movement will be made of the rotor in a clockwise direction. Under these circumstances the detent member 38 leaves the position illustrated between the detent cams 53 and 54 and travels over the detent cam 54 into a position between the detent cams 54 and 55 wherein it will be indexed to the next successive position in a clockwise direction.
  • the resiliently deformable beam is moved radially inwardly as the detent member 38 passes over the detent cam 54.
  • a similar operation occurs with respect to the beam 27 land the detent member 28 as it passes over the detent cam 59.
  • the central body portion 26 of the rotor 23 contains a plurality of platforms 71 through 74 each having a tab 75 through 78 respectively extending outwardly therefrom.
  • Each of the tabs 75 through 78 is adapted to receive an opening provided within the movable contact element.
  • a plurality of contact elements may be afiixed to a rotor if such is desired. For example, if. a single pole switch is to be constructed a contact element would be afiixed to the tab 77, if a two pole switch is to be constructed then contact elements would be aflixed to tabs 75 and 77, since they are positioned upon the rotor 180 apart. In the event, however, that a three pole switch is desired movable contact elements would be afiixed to .tabs 76, 77 and 78 respectively since these are positioned 120 apart, thus leaving tab 75 vacant under these conditions.
  • the stop 35 positioned upon the rotor is vertically displaced upwardly from the detents 28 and 38.
  • the detent cams 51 through 60 operate either as detent cams or as a stop member depending upon the vertical height thereof along the side wall 14.
  • the stop 36 which cooperates with the stop member 35 as illustrated in FIG. 2 extends upwardly substantially the entire distance along the side wall 14 while on the other hand, the detent cam such as illustrated at 41 in FIG. 2 extends only upwardly in a vertical direction to a distance substantially the same as the height of the detent 38.
  • stops may be utilized along with a similar plurality of detents in accordance with any given switch construction desired for a particular application depending upon whether a single pole, a double pole or a triple pole switch is desired and whether stops will be utilized or whether the operation will be continuous in a rotary fashion.
  • FIG. 5 an alternative embodiment of a unitized rotor constructed in accordance with the present invention is illustrated.
  • the structure of the rotor is similar in all features with the exception that the resiliently deformable beam mem bers 81 and 82 are aifixed only at one end thereof such as at 83 and 84 respectively and are thus cantilevered from the central body portion 85 of the rotor mechanism.
  • the resiliently deformable beam mem bers 81 and 82 are aifixed only at one end thereof such as at 83 and 84 respectively and are thus cantilevered from the central body portion 85 of the rotor mechanism.
  • the particular configuration of the movable contact element may be more fully realized.
  • the electrical contact portion of the movable contact element is illustrated at 91 and has a forwardly extending portion 92 and a rearwardly extending portion 93.
  • a connector arm 94 extends from the contact portion of the contact element to a mounting portion 95 thereof which has an opening 96 provided therein.
  • mounting portion 95 is bent about a line 97 thereof in order to conform to the mounting tabs 75 through 78 as shown in FIG. 4 formed upon the bottom side of the rotor mechanism.
  • the arm 94 is connected to the electrical contact portion 91 of the movable contact element at a point closer to the rear section 93 thereof than to the forward section 92.
