A control knob for an appliance includes an outer control ring, a stationary hub, a rotation modulating mechanism coupled to the outer control ring and engaged with an outer surface of the stationary hub, wherein the outer control ring is rotationally operable about the stationary hub at a first rate, an indicial ring positioned around the stationary hub, wherein the indicial ring engages a portion of the rotation modulating mechanism, wherein rotation of the outer control ring at the first rate causes the rotation modulating mechanism to rotate the indicial ring about the stationary hub at a second rate, the second rate being different than the first rate and an encoder shaft positioned within the stationary hub, wherein an inner gearing mechanism extends between an exterior surface of the encoder shaft and one of the outer control ring and the indicial ring.

A lever switch includes: an operation lever including an operation portion to which an operation load is to be applied, and configured to swing around a rotation axis; a first drive lever driven by the operation lever and configured to swing around a first fulcrum to drive a first switch in response to the operation lever being operated around the rotation axis in a first direction; and a second drive lever driven by the operation lever and configured to swing around a second fulcrum to drive a second switch in response to the operation lever being operated in a second direction opposite to the first direction. When projected onto a plane orthogonal to the rotation axis, the first and second fulcrum are disposed on the same side with respect to a virtual straight line passing through the operation portion and the rotation axis, and separated from the virtual straight line.

A docking and locking mechanism includes a handle actuatable between a docked position and an undocked position and an eccentric mechanism coupled to the handle, the eccentric mechanism having a rod that rotates in an eccentric path upon actuation by the handle. The docking and locking mechanism also includes a linkage assembly with a plurality of sleeves and linkage shafts coupling the rod of the eccentric mechanism to a docking lever assembly having a docking lever to enable actuation of the docking lever.

A control device for an aircraft is disclosed including a push-button switch that is configured to be held in a depressed position by a pilot during taxiing of the aircraft. The push-button switch is configured to return automatically to a released position if it is not held in the depressed position by the pilot. The control device is configured to output a command for braking to a braking system of the aircraft, if the push-button switch moves to the released position during taxiing of the aircraft and does not return to the depressed position within a set time. The button may be provided on a tiller. A method of detecting on-board pilot incapacitation during an aircraft taxi phase is also disclosed.
