Abstract
Abstract In a joystick control switch having an operating lever rotatable about a point intermediate the length of the lever, the lever is positively indexable in each of a plurality of positions of rotation by means of a collar slidably mounted on the lever and resiliently biased into engagement with a gate member defining the plurality of positions of rotation, and in each of the plurality of positions of rotation the lever operates a depressible-plunger-type switch by contact of the lever with the plunger either directly or through the intermediary of a single lever member. A button located in one end of the lever is depressible to slide a shaft extending longitudinally of the lever to depress the plunger of an additional switch at the other end of the lever, in one position of rotation of the lever.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
Joystick control switch means, comprising a support (14, 16) containing an opening; a lever (10) pivotally connected intermediate its ends in said support opening, thereby defining first and second lever portions on opposite sides of said support, said lever being pivotally operable upon manual displacement of said first portion; gate means (18) connected with said support for cooperation with said second lever portion to define a plurality of pivotal positions of said lever relative to said support; abutment means (24) mounted for longitudinal sliding movement on said second lever portion; means (26) resiliently biasing said abutment means into engagement with said gate means for positively indexing said lever in said pivotal positions, respectively; and a plurality of switching means (36, 38, 40, 42) connected with said support for selective operation by said second lever portion in accordance with the corresponding pivotal position of said lever, respectively.
Claim 2
Dependent Claim
146 words
Joystick control switch means, comprising a support (14, 16) containing an opening; a lever (10) pivotally connected intermediate its ends in said support opening, thereby defining first and second lever portions on opposite sides of said support, said lever being pivotally operable upon manual displacement of said first portion; gate means (18) connected with said support for cooperation with said second lever portion to define a plurality of pivotal positions of said lever relative to said support; abutment means (24) mounted for longitudinal sliding movement on said second lever portion; means (26) resiliently biasing said abutment means into engagement with said gate means for positively indexing said lever in said pivotal positions, respectively; and a plurality of switching means (36, 38, 40, 42) connected with said support for selective operation by said second lever portion in accordance with the corresponding pivotal position of said lever, respectively.
Claim 3
Dependent Claim
45 words
A joystick control switch as claimed in claim 1, and further comprising a plurality of housing means containing respective ones of said switching means and a plurality of plunger means projecting from respective housing means and depressible to operate respective ones of said switching means.
Claim 4
Dependent Claim
29 words
A joystick control switch as claimed in claim 2 wherein at least one of said plunger means is depressible through direct contact by said second portion of said lever.
Claim 5
Dependent Claim
57 words
A joystick control switch as claimed in claim 3 wherein said lever includes respective first and second ends adjacent said first and second portions of said lever, and said one plunger means is depressible through direct contact by said second portion adjacent said second end, and said abutment means comprises a collar member encircling said second portion.
Claim 6
Dependent Claim
34 words
A joystick control switch as claimed in claim 3 further comprisinG lever means rotatable through direct contact by said second portion to depress said plunger means of a further one of said switching means.
Claim 7
Dependent Claim
68 words
A joystick control switch as claimed in claim 1, wherein said lever includes respective first and second ends adjacent said first and second portions, and further comprising additional switching connected with said support adjacent the second lever portion, means and button means located in said first end and manually depressible to operate said additional switching means in one of said plurality of positions of rotation of said lever.
Claim 8
Dependent Claim
90 words
A joystick control switch as claimed in claim 6 wherein said additional switching means includes plunger means depressible to operate said additional switching means, and further comprising a shaft extending through said lever longitudinally thereof and slidable relative to said lever, resilient bias means for urging said shaft in one direction relative to said lever, said lever being slidable in the opposite direction upon depression of said button means to contact and depress said plunger means of said additional switching means in said one position of rotation of said lever.
Claim 9
Dependent Claim
28 words
A joystick control switch as claimed in claim 7 further comprising means for latching said button means when depressed in said one position of rotation of said lever.
Claim 10
Dependent Claim
25 words
