  • Patent number: 7199314
    Abstract: A joystick includes a base and a cover mounted over the base. A stick has a first end that extends from the cover and a second end. An active yoke is mounted above the base and is coupled to second end of the stick. The active yoke has a first and second end. The active yoke is adapted to be moved by the stick. A passive yoke is mounted over the active yoke and has a third and fourth end. The passive yoke is adapted to be moved by the stick. A first contactor is mounted to the first end and a second contactor is mounted to the third end. A first resistor is positioned between the first contactor and the cover and a second resistor is positioned between the second contactor and the cover. The resistors are adapted to generate an electrical signal that is indicative of a position of the stick. A switch is positioned in the base below the active yoke. The switch is activated when the stick is sufficiently depressed so as to cause the active yoke to contact the switch.
