The locking unit includes a rotary wheel which includes a main body fixed to the rotary shaft and latching teeth formed at a periphery of the main body and distributed in a ring around a central axis of the rotary wheel, a gap being defined between two neighboring teeth, an iron core configured to be inserted into the gap to limit rotation of the rotary wheel, and a solenoid connected to the iron core for driving the iron core to move. The knob device can realize locking of the rotary wheel clockwise and counter-clockwise, meeting requirement of diverse use.

The invention relates to an operating device for a motor vehicle, comprising an operating element, which can be lowered by application of force; a snap dome arranged below the operating element for applying haptic feedback to the operating element when the snap dome is deformed by means of the operating element lowering; a blocking body made of an electroactive polymer arranged below the operating element and next to the snap dome, the shape of which blocking body can be altered depending on an electrical voltage applied thereto such that lowering of the operating element is blocked or lowering of the operating element for deforming the snap dome is enabled; a detection apparatus for detecting a contact position of a finger on the operating element; a control apparatus which is set up to adjust a voltage at the blocking body depending on the detected contact position of the finger. The invention further relates to a method for operating an operating device and to a motor vehicle comprising an operating device of this kind.

An operation element is disposed in a recess provided in a lower surface of a controller attached to a vehicle ceiling part, and the operation element comprises an inclined portion inclined at an upward gradient from a vehicle front toward a vehicle rear, a protruding portion formed by the inclined portion, and provided on a vehicle front side of a point, on the operation element, that has an equal distance from opposite ends of the operation element in a front-back direction, and an operating rotary shaft disposed on a side of the protruding portion.

A load detection sensor unit 1A includes: a load detection sensor 5 that has a sensor sheet 50 having a pair of resinous insulating sheets 56s and 57s, a first electrode 56e provided on a surface of one insulating sheet 56s, and a second electrode 57e forming a pair with the first electrode 56e, and a metal plate 60 provided in at least a portion overlapping with the first electrode 56e and the second electrode 57e on one surface of the sensor sheet 50; and a pressing member 4 that has a pressing portion 46 disposed on the side of the metal plate 60 opposite to the side of the sensor sheet 50 and pressing the metal plate 60. The pressing portion 46 is harder than the seat cushion SC and the sensor sheet 50 and the metal plate 60 are bonded by an adhesive layer 70.

A foot pedal for controlling a medical device, in particular a dental device, including a housing with a housing base, a cover element which is mounted so as to be vertically displaceable with respect to the housing base along an actuating direction and so as to be inclinable with respect to the housing base, a first switch for initiating a first functionality on the medical device and a second switch for initiating a second functionality on the medical device, and an actuating device which is vertically displaceable along the actuating direction and which actuates the first switch during a movement in the actuating direction within a first height offset section and actuates the second switch within a second height offset section, the actuating device being configured in such a way, in that it is in a first state in the first height offset section and in a second state in the second height offset section, where the foot pedal being configured such that, at a predeterminable angle of inclination of the cover element, the actuating device is always arranged within the first height offset section.

A switch blocking device that is insertable into an open switch that prevents the switch from being closed, the device being sized and shaped to fit securely in a space between an open blade of the switch and fixed electrical contacts of the switch, the device having a handle that enables easy insertion and removal while also covering the live electrical blade.

An electronic switch includes a rubber sheet that includes a first surface, a second surface opposite to the first surface, and a convex portion on the first surface. The convex portion of the rubber sheet includes a semispherical shape.

A method for selectively restricting movement of an appliance position switch from a closed position to an open position includes positioning the pin within a channel of a body portion of a switch retention device and moving the body of the switch retention device in a first direction into an opening in a face of the appliance within which the pin is moveable from the open position to the closed position. Such movement is carried out to cause movement of the pin in the first direction toward the closed position. The method further includes continuing to move the switch retention device in the first direction such that a cap thereof contacts the face, and a tab extending outwardly from the body engages with the opening to retain the switch retention device in the opening and the pin in the closed position.

A trigger assembly for use with an electrical device, said electrical device having an electric switch housing with an electrical switch unit disposed therein, the trigger assembly including; a trigger member configured for movement relative to the housing; an actuator member operably-connected to the trigger member and, responsive to movement of the trigger member relative to the housing, said actuator member being movable in a first direction relative to the housing from an OFF position in which the electrical switch is operably-opened by the actuator towards an ON position in which the electrical switch is operably-closed by the actuator, and movable in a second direction relative to the housing from the ON position towards the OFF position; a lock-on mechanism including a first locking member mounted proximate to the trigger member and a second locking member mounted proximate to the housing, wherein when the actuator member is moved in to the ON position, said first and second locking members are selectably movable relative to each other into at least one of a locked configuration whereby the actuator member is locked in the ON position, and, an unlocked configuration whereby the actuator member is not locked in the ON position; and a lock-off mechanism including a lock-off member disposed on the trigger member, said lock-off member being rotatably movable about a first rotation axis between at least one of a locked-off position in which the lock-off member restricts movement of the trigger member relative to the housing and whereby the actuator member is restricted from being moved from the OFF position in to the ON position, and, a non-locked-off position in which the lock-off member does not restrict movement of the trigger member relative to the housing and whereby the actuator member is not restricted from being moved from the OFF position in to the ON position; and wherein the trigger assembly includes a shaped-portion disposed proximate to the housing wherein said shaped-portion is configured to abut against the lock-off member when the trigger member is moved towards the housing with the lock-off member rotatably arranged in to the locked-off position, whereby the actuator member is restricted from being moved from the OFF position in to the ON position.
