Abstract
Abstract An actuator for a switch construction and having an actuator shaft rotatably carried by a housing and being provided with cams thereon. An axially movable plunger is carried by the housing and has a plurality of abutments thereon cooperable with the cams. The plunger is rotatable to be set to one of a plurality of positions thereof relative to the housing so that the abutments cooperate with the cams in selected manners whereby the shaft must be rotated in a selected direction or directions to have one or more of the cams thereof cam against one or more of the abutments and thereby cause axial movement of the plunger to operate the switch construction interconnected to the actuator housing.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
146 words
An actuator for a switch construction comprising a housing having an opening, an actuator shaft rotatably carried by said housing and having cam means thereon, and an axially movable plunger carried by said housing and having abutment means thereon cooperable with said cam means, said plunger having a portion thereof projecting out of said opening and another portion thereof larger than sAid opening and disposed in said housing whereby said plunger cannot be removed from said housing through said opening, said plunger being settable to a plurality of positions relative to said housing while said other portion of said plunger is disposed in said housing so that said abutment means cooperate with said cam means in selected manners whereby said shaft must be rotated in the selected direction to having said cam means thereof cam said abutment means and thereby cause axial movement of said plunger.
Claim 2
Dependent Claim
146 words
An actuator for a switch construction comprising a housing having an opening, an actuator shaft rotatably carried by said housing and having cam means thereon, and an axially movable plunger carried by said housing and having abutment means thereon cooperable with said cam means, said plunger having a portion thereof projecting out of said opening and another portion thereof larger than sAid opening and disposed in said housing whereby said plunger cannot be removed from said housing through said opening, said plunger being settable to a plurality of positions relative to said housing while said other portion of said plunger is disposed in said housing so that said abutment means cooperate with said cam means in selected manners whereby said shaft must be rotated in the selected direction to having said cam means thereof cam said abutment means and thereby cause axial movement of said plunger.
Claim 3
Dependent Claim
25 words

Claim 4
Dependent Claim
23 words
An actuator as set forth in claim 2 wherein said plunger has opposed ends, one of said ends having said abutment means thereon.
Claim 5
Dependent Claim
25 words
An actuator as set forth in claim 3 wherein said abutment means comprises a plurality of abutments projecting from said one end of said plunger.
Claim 6
Dependent Claim
16 words

Claim 10
Dependent Claim
28 words
An actuator as set forth in claim 1 wherein said housing has stop means for limiting rotational movement of said shaft in each direction of rotational movement thereof.
Claim 11
Dependent Claim
29 words
An actuator as set forth in claim 9 wherein said cam means of said shaft abut said stop means to determine the limits of rotational movement of said shaft.
Claim 12
Dependent Claim
196 words
In combination, a switch construction having an operator therefor, an actuator for said switch construction and comprising a housing detachably interconnected to said switch construction and having an opening facing said switch construction, an actuator shaft rotatably carried by said housing and having cam means thereon, and an axially movable plunger carried by said housing and having abutment means thereon cooperable with said cam means, said plunger having a portion thereof projecting out of said opening and another portion thereof larger than said opening and disposed in said housing whereby said plunger cannot be removed from said housing through said opening, said plunger being associated with said operator to actuate the same when said plunger is moved to a certain axial position thereof, said plunger being settable to a plurality of positions relative to said housing while said other portion of said plunger is disposed in said housing so that said abutment means cooperate with said cam means in selected manners whereby said shaft must be rotated in the selected direction to having said cam means thereof cam said abutment means and thereby cause said axial movement of said plunger to said certain axial position thereof.
