A lighting control operating unit generating digital adjusting commands which are transmitted to a processing unit via a data link includes several control elements, including key buttons, slide controls and/or rotary controls, which are disposed at the upper side of a housing. At least one dual encoder is provided in a control panel of the lighting control operating unit allowing users to enter input values. The dual encoder presents a first shaft rotatably mounted in a housing, and a second shaft mounted in the housing so as to be coaxially rotatable, and corresponding first and second rotation signal generators Both shafts include actuating elements transmitting adjusting movements. The actuating elements are a rotary disk and/or a rotary swivel configured to be coaxially turned in opposite directions.

A gearbox below a grain bin floor can have a shift coupling movable between a drive position and a neutral position. A control rod can be axially movable between a corresponding drive position and a corresponding neutral position. A pair of biasing members can be operably positioned between the control rod and the shift coupling to bias the shift coupling in opposite directions. The opposite biasing forces of the biasing members can act against each other to bias the control rod into the neutral positioning recess to retain the external shift coupling and the control rod in the neutral position and the corresponding neutral position, respectively. The opposite biasing force of the biasing members can bias the control rod into the drive positioning recess to retain the external shift coupling and the control rod in the drive position and the corresponding drive position, respectively.

A fader device according to an aspect of the present invention includes: a guide rail that extends linearly and a slider that slidably engages with the guide rail, in which the slider includes a pressure-contact member that is to be in pressure contact with the guide rail, and a compression coil spring for jutting the pressure-contact member toward the guide rail.

An operation device includes an operation unit including an operation body worked by an operator's manipulation; a position detecting part detecting a position of the operation body; and a display unit displaying a position of the operation body. The display unit includes an operation member, a supporting body, and a movable load applying mechanism including a movable member, a magnetic generating mechanism, a magnetorheological fluid, and an operation controlling part. The display unit includes a display part displaying the operation position. A display controlling part PS controls a display. A controller is included to control the operation controlling part and the display controlling part. In a control method of the operation device, the controller controls to display a state of the operation position of the operation body on the display part.

A control device includes a housing and a button received within the housing. The housing defines a through hole and a latching slot. The button defines a pressing portion and a resilient arm. The pressing portion is slidably mounted within the through hole. One end of the resilient arm is coupled to the pressing portion, and a second end of the resilient arm is latched within the latching slot. When the pressing portion is pressed, the pressing portion slides to trigger a signal transmitting mechanism within the housing to emit a signal and causes the resilient arm to deform. When the pressing portion is released, the resilient arm is resiliently restored to cause the pressing portion to return to an initial position.

A manually operable control device for controlling moveable elements of a vehicle is disclosed. The control device may comprise a control rod element, which may be mounted so as to be slidable within a first guide path of a first control disc and within a second guide path; and the two control discs may be mounted so as to rotate independently of one another about a common axis in a continuous manner.

An input device is provided to supply multiple input from a button. The input device may include a first switch and a second switch. The input device may further include a slide button on a surface of the input device. The slide button may actuate the first switch when the slide button slides along a first direction substantially parallel to the surface of the input device. The slide button may actuate the second switch when the slide button slides along a second direction substantially parallel to the surface of the input device. The input device may further include a third switch. The slide button may actuate the third switch of the input device when the slide button is pressed towards the surface of the input device.

An operator mechanism for a control enclosure includes a shaft assembly having an adjustable length. A shaft extender may be selectively slidable longitudinally along an operator shaft to selectively adjust the length of the shaft assembly, and selectively lockable on the operator shaft to inhibit sliding of the shaft extender on the operator shaft to retain a selected length of the shaft assembly. A shaft extender may be received in a longitudinal passage of a mount sleeve and extend distally outward from the mount sleeve. The shaft extender may be selectively movable longitudinally within a longitudinal passage of the mount sleeve relative to a shaft operator to selectively adjust the length of the shaft assembly.

A lighting control operating unit generating digital adjusting commands which are transmitted to a processing unit via a data link includes several control elements, including key buttons, slide controls and/or rotary controls, which are disposed at the upper side of a housing. At least one dual encoder is provided in a control panel of the lighting control operating unit allowing users to enter input values. The dual encoder presents a first shaft rotatably mounted in a housing, and a second shaft mounted in the housing so as to be coaxially rotatable, and corresponding first and second rotation signal generators Both shafts include actuating elements transmitting adjusting movements. The actuating elements are a rotary disk and/or a rotary swivel configured to be coaxially turned in opposite directions.

A lighting control console for controlling a lighting system includes at least one digital processor, at least one digital memory, and at least one display device configured to graphically depict graphic elements for users. At least one dual encoder is provided in the control panel, which allows users to enter input values. The dual encoder presents a first shaft rotatably mounted in a housing with a first rotation signal generator and a second shaft mounted in the housing so as to be coaxially rotatable at the dual encoder. Both shafts include actuating elements transmitting adjusting movements onto the shafts. The actuating elements are embodied in a rotary disk and/or of a rotary swivel disposed in the control panel of the lighting control console and configured to be coaxially turned in opposite directions.
