Abstract
In a joystick controller for electric switches, a resilient bias is provided, biasing the joystick to its neutral position, by means of a garter spring which encircles and embraces two ring members, one ring member being displaced in its own plane in response to pivoting the joystick about its pivot and the other ring member being secured to a fixed housing part. The two ring members are profiled so that the garter spring rides from them upon pivoting the joystick through greater than a threshold angle from its neutral position, so that the bias is removed and the joystick stays put.
