## Abstract

A joystick apparatus includes a tiltably mounted tube and a rod reciprocally movably axially therethrough. The tube has a frustoconical first actuator at one end thereof for operating engagement with a selected one or more of a plurality of first switches as the tube is tilted. The adjacent end of the rod carries a part-spherical second actuator for operating engagement with a second switch when the rod is extended from the tube, the shape of the second actuator keeping it in proper operating relationship with respect to the second switch regardless of the position of the tube.

## Claims

### Claim 1

Joystick apparatus comprising a tube having an axis, a rod reciprocally movable in said tube axially thereof between a withdrawn position and an extended position, first actuator means mounted on said rod, second actuator means attached to said tube, first switch means disposed for operation by said first actuator means when said rod is disposed in the extended position thereof, a plurality of second switch means disposed around said second actuator means, and mounting means disposed intermediate the ends of said tube and defining a fulcrum point thereat and supporting said tube for tilting movement about said fulcrum point to effect movement of said second actuator means for operation of a selected one or more of said second switch means, said first actuator means being constructed and arranged for cooperation with said rod to be in position to operate said first switch means in any tilting orientation of said tube.

### Claim 2 (depends on 1)

The joystick apparatus of claim 1, and further comprising a handle encompassing at least a portion of said tube.

### Claim 3 (depends on 2)

The joystick apparatus of claim 2, wherein one end of said rod is recessed within said handle, and further comprising a plunger reciprocally carried by said handle and having a thumb engagement surface at one end thereof and a rod engagement surface at the other end thereof engaging said one end of said rod.

### Claim 4 (depends on 2)

The joystick apparatus of claim 2, and further comprising means carried by said handle for biasing said rod to the withdrawn position thereof.

### Claim 5 (depends on 1)

The joystick apparatus of claim 1, wherein one end of said rod projects from one end of said tube adjacent to said first switch means, said second actuator means being disposed adjacent to said one end of said tube.

### Claim 6 (depends on 1)

The joystick apparatus of claim 1, wherein said first actuator means is disposed between said rod and said first switch means.

### Claim 7 (depends on 6)

The joystick apparatus of claim 6, wherein said first actuator means includes a part-spherical engagement surface.

### Claim 8 (depends on 5)

The joystick apparatus of claim 5, wherein said first actuator means is attached to said one end of said rod.

### Claim 9 (depends on 8)

The joystick apparatus of claim 8, wherein said first actuator means has a part-spherical engagement surface disposed for operating engagement with said first switch means.

### Claim 10 (depends on 5)

The joystick apparatus of claim 5, wherein said second actuator means is disposed between said one end of said tube and said fulcrum point.
