Abstract
Abstract Joystick switch comprises a handle attached to a support member carrying a ball member which rides in a socket fixed on a base. A straight length of resilient wire fixed to the base passes through an aperture defined by four discrete contacts in the base and into a bore in the ball member where it is slideably received. Arcuate movement of the handle causes lateral deflection of the wire into contact with the contacts to generate signals for x-y directional control. Die cast zinc circuitry in the base provides grounding for the wire and signal current for the contacts. Resilient return action for the handle is effected by an elastomeric ring in the base which bears on an annular surface of the support member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
219 words
A joystick switch comprising: a support member with an integral elongate handle, said support member carrying a ball member coaxially with said elongate handle, said ball member having a bore therein which is coaxial with the axis of said elongate handle, said bore slideably receiving a length of resilient wire which is straight when in an undeformed state, said wire extending beyond said ball member, a base member having socket means thereon, said base member having an aperture extending therethrough from said socket means, said socket means receiving said ball member therein, said wire extending into said aperture, said base member having four discrete contacts fixed therein and situated radially about said aperture, the center of said aperture being coaxial with said handle when said wire is in an undeformed state, said straight length of wire passing clearly through said aperture when said wire is in an undeformed state, said wire being fixed relative to a surface of said base opposite said aperture from said socket means, first resilient means between said support member and said base member, said first resilient means urging said support member toward a position where said wire is straight, whereby, arcuate movement of said handle will cause said ball member to rotate in said socket means and said wire to deflect toward said contacts.
Claim 2
Dependent Claim
219 words
A joystick switch comprising: a support member with an integral elongate handle, said support member carrying a ball member coaxially with said elongate handle, said ball member having a bore therein which is coaxial with the axis of said elongate handle, said bore slideably receiving a length of resilient wire which is straight when in an undeformed state, said wire extending beyond said ball member, a base member having socket means thereon, said base member having an aperture extending therethrough from said socket means, said socket means receiving said ball member therein, said wire extending into said aperture, said base member having four discrete contacts fixed therein and situated radially about said aperture, the center of said aperture being coaxial with said handle when said wire is in an undeformed state, said straight length of wire passing clearly through said aperture when said wire is in an undeformed state, said wire being fixed relative to a surface of said base opposite said aperture from said socket means, first resilient means between said support member and said base member, said first resilient means urging said support member toward a position where said wire is straight, whereby, arcuate movement of said handle will cause said ball member to rotate in said socket means and said wire to deflect toward said contacts.
Claim 3
Dependent Claim
88 words
A joystick switch as in claim 1 wherein said wire is electrically continuous with a ground circuit trace carried on said surface of said base where said wire is fixed thereto, and each of said contacts is electrically continuous with a respective signal circuit trace carried by said base, whereby arcuate movement of said handle will complete a circuit between a signal circuit trace and said ground circuit trace as said handle is moved arcuately and said wire contacts at least one of said contacts about said aperture.
Claim 4
Dependent Claim
25 words
A joystick switch as in claim 2 wherein said circuit traces are cast metal, said signal circuit traces being cast continuously with said signal contacts.
Claim 5
Dependent Claim
12 words
A joystick switch as in claim 3 wherein said metal is zinc.
Claim 6
Dependent Claim
75 words
A joystick switch as in claim 1 wherein said four discrete contacts are situated in a plug receiving passage through said base member from said surface to said socket means, said passage receiving a support plug closely therein, said plug being profiled to receive said contacts therein thereby positioning said contacts, said plug having a wire receiving passage therethrough, said wire passing through said aperture into said passage and being fixed relative to said plug.
Claim 7
Dependent Claim
34 words
The joystick switch of claim 1 wherein said discrete contacts have gaps therebetween which are smaller than the diameter of said wire, whereby said wire can bridge two signal contacts without being deflected therebetween.
Claim 8
Dependent Claim
84 words
The joystick switch of claim 1 wherein said resilient means comprises a ring-shaped elastomeric member carried on said base concentrically with said socket means, and said support member comprises a hemispherical member having a convex side and a concave side, said handle extending from said convex side and said ball member extending from said concave side, said hemispherical member having an annular surface between said concave and convex sides, said elastomeric member bearing against said annular surface resiliently when said handle is moved arcuately.
