  • Patent number: 5225831
    Abstract: A joystick and associated circuit including a joystick handle and angularly oriented opposed pairs of first and second switches positioned apart from each other on respective axes, the switches being selectively actuatable by movements of the handle, and a resistive path connected to each pair of opposed switches between an operating voltage source and an output terminal, each resistive path providing selected resistance to the respective output terminal which is representative of corresponding movements of the handle, each resistive path including resistive elements connected between the operating voltage source and the respective output terminal, activation of the switches causing the resistance of the respective resistive path to be altered to provide different resistive values to the output terminal.
