Abstract: A joystick (1) having a yoke pivotally secured to an upper support (28) and a lever (16) pivotally secured to a lower support. The yoke has a latching portion that engages a cam roller (14) on the lever to push the lever downward. Supported on the lever is an armature (24) positioned in spaced relation to a solenoid (26).

Abstract: A joystick controller includes a pivoted lever, a main bush carried on the lever and co-operating with a cam surface, and a secondary bush carried on the lever and biased against an inclined surface of the main bush to bias the main bush against the cam surface. The secondary bush abuts a stop when the lever is pivoted through a predetermined angle parallel to a major axis of displacement such that farther displacement in the same direction causes the secondary bush to slide along the inclined surface of the main bush and displace along the lever against the bias. Accordingly, increased resistance to displacement is provided.
