A button structure includes a first component, a second component, and a pressing element mounted on the second component. The first component has a first base portion. The first base portion protrudes outward to form at least one first extending portion. The at least one first extending portion protrudes inward to form a limiting portion. The second component has a second base portion. The second base portion protrudes rearward to form at least one second extending portion. The at least one first extending portion and the at least one second extending portion are connected by a pivoting assembly. The at least one second extending portion protrudes rearward to form a blocking portion. When the blocking portion is pivoted on the first component, the blocking portion is alternatively located to a bottom of the limiting portion and a top of the limiting portion.

Various examples of park brake interface modules which are utilized as human machine interfaces (HMI) in vehicles are provided. In one example, a park brake interface module for a vehicle includes a park brake switch device to actuate the park brake. The park brake switch device is capable of actuating the vehicle park brake in a brake apply mode upon receipt of a pinch signal. In another example, the park brake interface module includes a park brake switch device which is capable of actuating the vehicle park brake in a brake release mode upon receipt of a reach signal. In a further example, the park brake interface module includes recessed fixed parking brake actuation switches. In operation, the electronic interface module and park brake switch devices allow the operator to apply or release the vehicle park brakes according to memorable mnemonics, for example, “pinch to park” and “reach to release.”

A command device for controlling a mechanical energy reduction assembly of an aircraft, movable between an inactive configuration and a maximum mechanical energy reduction configuration, includes a rocker button, movable between a mechanical energy reduction assembly configuration maintaining position, a first position of incremental movement of the mechanical energy reduction assembly to its maximum mechanical energy reduction configuration and a second position of incremental movement of the mechanical energy reduction assembly to its inactive configuration. The command device further includes at least one return element configured to return the rocker button to its maintaining position.

A control system is for a high lift assembly of an aircraft. The assembly is controllable in two aerodynamic configurations each with different lift. The control system includes a manual control device operable by a pilot of the aircraft. The manual control device includes at least one member movable relative to a base body. The movable member can be moved relative to the base body between a rest position, a first position and a second distinct position. The manual control device includes a resilient return device for the movable member in the rest position. The manual control device issues a signal when the movable member reaches either the first or second position, to move the high lift assembly between two of the aerodynamic configurations.

A steering bar for a lever-controlled vehicle provides for single hand operation of the lever-controlled vehicle. For example, the steering bar couples to the control levers for a zero-turn mower, providing safer, easier operation of the mower and making the mower handicap accessible. The steering bar can easily be installed on any dual steering zero turn mower. Steering is easier because turning it controlled by rotating the steering bar either right or left, with control of forward and reverse movements by pushing or pulling the bar. Speed, turning direction, or motion forward or reverse are all controlled by a single bar with a single hand. The steering bar is coupled with a selectively extensible control shaft to accommodate for the differing displacement length between the control levers during turning movements. The steering bar is coupled with the control levers with a ball and socket joint.

A control lever assembly for controlling an aircraft system. The lever includes: a housing having an outer side and an aperture defined by a rim; and a control lever extending through the aperture and movable in the aperture; the control lever having an outer cover member arranged to slide over the outer side of the housing and cover the rim throughout the range of movement of the control lever.

A vehicle operating device including an operating member operable by a driver and configured to: issue, to a drive system, a command to apply a drive force in a forward direction when a first-direction operation of the operating member from its neutral position in a first direction is performed in a state in which the vehicle is at a stop or running forward; issue, to the drive system, a command to apply a drive force in a backward direction when a second-direction operation of the operating member from the neutral position in a second direction different from the first direction is performed in a state in which the vehicle is at a stop or running backward; and issue, to a brake system, a command to apply a braking force as an opposite-direction-operation-dependent braking force when the second-direction operation is performed in a state in which the vehicle is running forward.
