  • Patent number: 6654005
    Abstract: A joystick has a base and a cover mounted over the base. A stick has a first end extending from the cover and a second end. A gimbal has a first and second yoke that are coupled to the stick to allow the stick to move. The yokes each have a first and second end. A pair of wipers is mounted to the first ends of the yokes. A pair of resistors is positioned between the wipers and the base. The resistors are adapted to generate an electrical output signal indicative of a position of the stick when a voltage is applied to the resistors. Several terminals are mounted to the base. A first portion of the terminals are electrically connected to the resistors. A switch is positioned in the base below the second end of the first yoke. The switch is activated when the first yoke is sufficiently rotated so as to cause the second end of the first yoke to contact the switch and to close the switch.

  • Publication number: 20030189547
    Abstract: A joystick that has a low profile or height. The joystick has a housing with an inner cavity and a top surface. An aperture is located in the top surface. A stick assembly extends through the aperture. A gimbal assembly is located in the cavity and has the stick assembly mounted thereon. A pair of variable resistors are mounted to the gimbal assembly. The resistors generate an output signal indicative of a position of the stick assembly. A first set of terminals are electrically connected to the resistors and extend parallel to the stick assembly from the top surface. A second set of terminals are attached to the housing and extend from the top surface parallel to the stick assembly.
