A control lever device of an industrial vehicle includes a control lever that is tiltable forward and rearward relative to a vehicle body of the industrial vehicle and that includes a control knob, a switch button that is provided on the control knob and adapted to be pushable while the control lever is operated. The switch button has a movement axis indicating a movable direction of the switch button. The movement axis is inclined forward relative to a direction orthogonal to an extending direction of the control knob so that a pushing direction of the switch button is directed rearward from the direction orthogonal to the extending direction of the control knob.

A safety switch device includes a first support member and a second support member which are formed so as to secure a mobile terminal, and a grip part to be grasped by an operator's hand. The safety switch device includes an enable switch for transmitting a signal for permitting a robot to operate, and an emergency stop button for transmitting a signal for stopping the robot. The first support member and the second support member are formed so as to secure a plurality of types of mobile terminals having different sizes. The grip part is disposed at the center part of the shape of the back surface of the mobile terminal, which corresponds to the position of the center of gravity of the mobile terminal.

An operation device includes a main body, a lifting and lowering mechanism unit movably supported with respect to the main body and including a driven portion configured to receive driving force for movement of the lifting and lowering mechanism unit, a driving unit attached to the main body and configured to drive the lifting and lowering mechanism unit by a driving pin provided on a rotation gear. The lifting and lowering mechanism unit includes a groove portion into which the driving pin is accommodated by rotation of the rotation gear when the driving unit is mounted on the main body.

An improvement is achieved in workability in an operation of assembling an operation input device having a function of applying a reaction force in response to a movement of an operation button. An input device (100) has an operation button (20), a movable member (30) capable of pushing the operation button (20) toward an initial position, and an electric motor (35) that moves the movable member (30). The input device (100) has a holder (40) that holds the electric motor (35). The holder (40) supports the operation button (20) and the movable member (30) so as to permit movement of the operation button (20) and the movable member (30).

A control knob for an appliance includes a base having an axially-operated switch. An outer control assembly is rotationally and axially operable with respect to the base. An inner display assembly is rotationally fixed with respect to the base and axially fixed with respect to the outer control assembly. The inner display assembly is biased toward an extended state and is axially operable to a selection state that engages the axially operated switch.

A haptic interface, including: a button which can be rotated by a user; an interaction element interacting with a magnetorheological fluid, secured to the button; a mechanism measuring a current position of the button; a brake including a magnetorheological fluid and a generation system to generate a magnetic field in the fluid; a controller configured to generate orders for the system to generate a magnetic fluid to modify a value of the magnetic field; and a mechanism to detect torque exerted by a user on the button to know direction of the torque and whether the torque is greater than a given value for a given direction, the controller controlling generation of a magnetic field based on obtained information about the torque at least when the button indicates zero or low speed.
