Abstract
Abstract Joystick switch comprises a handle attached to a contact carrying support member which is latchably carried by latch arms attached to a contact carrying base member. Contacts are cast in loop-like patterns toward the periphery of each member and an elastomeric member inside the bounds of the contacts between the support member and base provides resilient return action. A plunger carried in a bore in the handle and through the elastomeric member closes contacts in the base and is operated independently of the joystick directional control.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
162 words
A joystick switch assembly which comprises: an elongate handle; a base member lying in a plane extending transversely of the axis of said handle, said base member having first contact means thereon; a support member integral with said handle which supports said handle for arcuate movement, said support member moving relative to said base member, said support member having second contact means thereon arranged to contact said first contact means upon moving said handle in a predetermined direction; a plurality of elongate latch arms integral with one of said members and extending between said base and said support member, said latch arms having distal ends with latches thereon which limit the relative movement of said support member away from said base member; said distal ends serving as pivot points for said arcuate movement of said support member; and first resilient means between said support member and said base member, said first resilient means urging said support member away from said base member.
Claim 2
Dependent Claim
162 words
A joystick switch assembly which comprises: an elongate handle; a base member lying in a plane extending transversely of the axis of said handle, said base member having first contact means thereon; a support member integral with said handle which supports said handle for arcuate movement, said support member moving relative to said base member, said support member having second contact means thereon arranged to contact said first contact means upon moving said handle in a predetermined direction; a plurality of elongate latch arms integral with one of said members and extending between said base and said support member, said latch arms having distal ends with latches thereon which limit the relative movement of said support member away from said base member; said distal ends serving as pivot points for said arcuate movement of said support member; and first resilient means between said support member and said base member, said first resilient means urging said support member away from said base member.
Claim 3
Dependent Claim
50 words
A joystick switch as in claim 1 wherein said latch arms are integral with said base and extend substantially normal thereto, said distal ends being disposed about the periphery of said support member, said latches being cooperable with said support member to limit movement thereof away from said base member.
Claim 4
Dependent Claim
36 words
A joystick switch as in claim 2 wherein said support member has a like plurality of recesses in the periphery thereof, each said recess being positioned to receive the distal end of a respective latch arm.
Claim 5
Dependent Claim
40 words
A joystick switch as in claim 2 wherein said plurality of latch arms is four, said latch arms being disposed an equal distance apart, the distal ends thereof being spaced ninety degrees apart about the axis of said elongate handle.
Claim 6
Dependent Claim
16 words
A joystick switch as in claim 1 wherein said first contact means comprises four discrete contacts.
Claim 7
Dependent Claim
42 words
A joystick switch as in claim 5 wherein said discrete contacts are set in an octagonal channel in said base member, each contact occupying the full length of one leg and part of the length of two adjacent legs of said channel.
Claim 8
Dependent Claim
60 words
A joystick switch as in claim 6 wherein each contact has an exposed planar surface defined by a respective plane which is unique for each leg of the octagon, each contact thereby having three such planar surfaces, said planes all being only slightly canted from a common plane and converging at a common apex toward the center of said base.
Claim 9
Dependent Claim
18 words
A joystick switch as in claim 5 wherein said second contact means comprises a continuous loop of metal.
Claim 10
Dependent Claim
42 words
A joystick switch as in claim 1 wherein said first resilient means comprises a first elastomeric member axially disposed between said support member and said base, said first and second contact means being disposed about the periphery of said first elastomeric member.
Claim 11
Dependent Claim
78 words
A joystick switch as in claim 1 wherein said switch further comprises: continuous linear bore means axially through said handle and said support member, said bore means carrying elongate plunger means therein, said plunger means having a first end extending beyond the distal end of said handle and a second end extending beyond said support member and toward said base; and switch means mounted on said base proximate said second end of said plunger means and actuable thereby.
Claim 12
Dependent Claim
40 words
A joystick switch as in claim 10 wherein said first resilient means comprises a first elastomeric member axially disposed between said support member and said base, said member having aperture means axially therethrough, said aperture means accommodating said plunger means.
Claim 13
Dependent Claim
82 words
A joystick switch as in claim 11 wherein said switch means comprises: a third contact means in contact with said second end of said plunger means, said third contact means being movable relative to said base; fourth contact means stationary relative to said base and arranged to be contacted by said third contact means when said plunger means is advanced through said bore means toward said base; and second resilient means urging said third contact means away from said second contact means.
Claim 14
Dependent Claim
104 words
A joystick switch as in claim 12 wherein, said third contact means is a substantially flat piece of stamped and formed metal having an arcuate concave surface facing said second end of said plunger means and an annular brim surrounding said concave surface; said fourth contact means is a substantially cup-shaped piece of stamped and formed metal having a cylindrical section and an annular brim which faces said annular brim of said third contact means; said second resilient means is a second elastomeric member disposed in said cylindrical section and bearing against a convex surface opposite said concave surface of said third contact means.
Claim 15
Dependent Claim
20 words
The joystick switch of claim 1 wherein said first contact means is composed of metal cast on said base member.
Claim 16
Dependent Claim
20 words
The joystick switch of claim 1 wherein said second contact means is composed of metal cast on said support member.
