A joystick includes a mechanism for facilitating the changing of a grip assembly. An actuation mechanism moves a ram into a position where the operator can press down on a locking pin to release the grip assembly. The ram will be in a default position that does not interfere with the operations of the joystick during normal operation. A relatively low amount of force is used to place the ram into position as the force needed to press down on the locking pin comes from the operator. A small electromagnetic that does not interfere with the joystick operations can be used in the actuation mechanism.

Apparatus for removing a joystick grip

A rocker switch including a switching unit made up of a housing and including a spring-action switching element that moves back and forth with an actuating rocker that is connected to the switching element, whereby the switching element has a rotating axle rotatably supported within the housing and is surrounded by a spring. The spring is double wound and held in a prestressed state within the housing, one of the spring end shanks of the spring being fixedly supported within the housing, the other spring end shank being supported on a first arm that is connected in a rotationally fixed manner to the rotating axle, and an extended central spring leg being both fixedly supported within the housing as well as being supported on a second arm that is connected in a rotationally fixed manner to the rotating axle, and with an electrical switching unit.

Rocker switch

A handle () for controlling a machine, has a largely vertical shaft () forming a grip part () and has an upper end forming a receptacle () that holds switch units (-) and a lower end forming a hand rest (). The hand rest can be adjusted along the shaft () and can be detachably clamped to the shaft. The hand rest () comprises front and rear rest part () that are pivotally, or swivelably, connected to one another. To prevent unintentional opening of the hand rest () by axial pressure on the latter, the two rest parts () can be moved relative to one another in the axial direction to effect a locking and unlocking of their relative pivotabilities.

Handle grip

A rocker switch () is provided with a mechanical switch unit consisting of a switch housing () made of plastic, a switching element () supported in spring-loaded manner on said switch housing so as to be capable of moving back and forth, and an actuating rocker () connected to the switching element (), and also with limit-stop elements () for limiting the actuating angle of the actuating rocker (), and with an electrical switch unit. In order to obtain variable actuating angles and overcompression functions, the invention provides that the actuating rocker () is provided with an overcompression element () which in one or both of the actuating directions comes to be operationally connected to an overcompression stop () on the switch housing () before the limit-stop elements () come into operation.

The invention relates to a joystick having a hand-grip, which is mounted with two degrees of freedom in a mounting in a housing and which may be deflected in different directions out of an initial position, the grip being biased by a spring mechanism towards its initial position and sensor apparatus being provided to sense the different positions of the grip and to generate an output signal which may be used to control machine and/or vehicle functions. A housing cover ( ) is provided having its upper side directed towards the grip, while on the underside, there is pivotally mounted a cardan joint center portion ( ) on whose underside there is pivotally mounted a cardan joint inner portion ( ), whose underside is provided with spherical segments, which are mounted in complementary bearing cup-portions provided on a receiving support ( ).
