Abstract:
1. A joystick, comprising: a) a base; b) a cover mounted over the base; c) a stick having a first end extending from the cover and a second end; d) an active yoke mounted above the base and coupled to the second end, the active yoke having a first and second end, the active yoke adapted to be moved by the stick; e) a passive yoke mounted over the active yoke and having a third and fourth end, the passive yoke adapted to be moved by the stick; f) a first contactor mounted to the first end; g) a second contactor mounted to the third end; h) a first resistor positioned between the first contactor and the cover; i) a second resistor positioned between the second contactor and the cover; the resistors adapted to generate an electrical signal indicative of a position of the stick when a voltage is applied to the resistors; j) a plurality of terminals mounted to the base, a first portion of the terminals electrically connected to the resistors; and k) a switch, positioned in the base below the active yoke, the switch activated when the stick is sufficiently depressed so as to cause the active yoke to contact the switch and to close the switch, the switch electrically connected to a second portion of the terminals; and l) a spring mounted between the base and the active yoke, the spring biasing the active yoke, the passive yoke and the stick away from the base.
