Abstract
Abstract An actuator for limit switches including a relatively flat cam slide plate upon which a plurality of cams are mounted for adjustment within tracks, the cam slide plate being slidably disposed relative to a plurality of switches, a switch being aligned with each cam track wherein the cams may be selectively positioned within the associated track to provide a desired sequence of switch operation upon movement of the cam slide.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
172 words
A linear switch actuator comprising, in combination, a limit switch housing having a bottom wall, a plurality of limit switches mounted within said housing, a switch actuator connected to each of said switches and extending through said bottom wall, a cam slide track mounted on said housing adjacent said bottom wall, an elongated flat cam slide plate mounted in said track for linear slidable movement relative to said switch housing and said switch actuators having a length greater than the length of said switch housing in the direction of said slidable movement, a plurality of cam tracks defined in said slide extending substantially the length thereof and parallel to the direction of movement thereof, a cam track being aligned with each switch actuator, a cam mounted within each of said tracks, said cams actuating the switch actuator aligned with its associated cam track upon the movement of said slide to engage a cam with its aligned actuator, and means defined on said slide for connecting said cam slide to a movable member.
Claim 2
Dependent Claim
172 words
A linear switch actuator comprising, in combination, a limit switch housing having a bottom wall, a plurality of limit switches mounted within said housing, a switch actuator connected to each of said switches and extending through said bottom wall, a cam slide track mounted on said housing adjacent said bottom wall, an elongated flat cam slide plate mounted in said track for linear slidable movement relative to said switch housing and said switch actuators having a length greater than the length of said switch housing in the direction of said slidable movement, a plurality of cam tracks defined in said slide extending substantially the length thereof and parallel to the direction of movement thereof, a cam track being aligned with each switch actuator, a cam mounted within each of said tracks, said cams actuating the switch actuator aligned with its associated cam track upon the movement of said slide to engage a cam with its aligned actuator, and means defined on said slide for connecting said cam slide to a movable member.
Claim 3
Dependent Claim
92 words
A linear switch actuator as in claim 1 wherein said cam slide track includes a bridge member disposed between said cam slide and said switch housing and extending over said cam slide, said cams passing under bridge during operation of said slide, the distance between said bridge and cam slide in the direction of switch actuator movement being no greater than the maximum operating range of movement of said switch actuator and switches whereby said bridge protects said switches against excessive movement due to oversize cams being affixed to said cam slide.
Claim 4
Dependent Claim
60 words
A linear switch actuator as in claim 1 wherein said switch actuators each include a plunger slidably mounted in said actuator movable within given limits in the operative direction of movement, and a spring biasing each of said plungers away from the associated switch whereby said springs prevent over travel of said plungers toward said switches due to inertia forces.
Claim 5
Dependent Claim
44 words
In a linear switch actuator as in claim 3 wherein said plungers each include a first end disposed toward said cam slide, a semispherical recess defined in said first end and a ball rotatably received within said recess and engageable by the aligned cam.
Claim 6
Dependent Claim
37 words
In a linear switch actuator as in claim 1 wherein said cam slide track includes first and second oppositely disposed ends, said track ends being open wherein said cam slide may extend beyond said ends during operation.
