Abstract
A control device for producing electrical signals which correspond to manual movements of a stick part and which are used for adjustment of a controlled element has a relatively stationary body part with a hand supporting surface and a stick projecting outward from that surface to be embraced by an operator's hand. The stick comprises a laterally swingable outer stick part end-to-end with an inner stick part fixed to the body. A rod-like spring element in a chamber in the stick has an end portion fixed to each stick part to swingably connect the outer stick part of the inner one and bias the outer one to a neutral position. A signal emitting device in the chamber is mounted alongside the spring element and is operatively connected with it.
