A boat lift control system includes a first contactor switch and a second contactor switch. Each contactor switch, when activated, couples an AC voltage source to a boat lift motor. The first contactor switch includes a first override button. The first contactor switch is activated when the first override button is engaged. The second contactor switch includes a second override button. The second contactor switch is activated when the second override button is engaged. The first contactor switch and second contactor switch are positioned to linearly align the first override button with the second override button. An electrically non-conductive interface is adapted for user manipulation thereof resulting in engagement of the interface with one of the first override button and second override button.

A rolling-ball tilt switch includes a conductive housing having an inner surface that surrounds a longitudinal axis and that defines a roller cavity, an insulating seat inserted into the roller cavity, a conductive terminal having a protruding section extending through the insulating seat into the roller cavity, and a conductive rolling-ball disposed in the roller cavity and movable between a conducting position and a non-conducting position. The longitudinal axis and an extension of a surface portion of the inner surface of the conductive housing cooperatively define an angle ranging from 5 to 55 degrees.

A plurality of control elements extend from the base portion of a control module in a materials handling vehicle. The control elements are located adjacent to one another, wherein at least one of the control elements includes mounting structure that permits the control element to be selectively mounted to the base portion in at least first and second positions. The first position defines a first distance between the control element and an immediately adjacent control element and the second position defines a second distance between the control element and the immediately adjacent control element, the second distance being greater than the first.

An input device includes: a casing that includes a tubular portion in which an end portion of a column post is fitted, and to which a turn lever unit that a driver operates is attached, the column post rotatably supporting a steering shaft; and a biasing member disposed between a brim portion and the column post in a central axis direction of the tubular portion, the brim portion being provided on an inside surface of the tubular portion. The tubular portion includes an engaging portion that engages, in the central axis direction, with an engaged portion of the column post, and in a state in which the engaging portion is engaging with the engaged portion, the biasing member biases the brim portion in a direction in which the brim portion moves away from the column post, the direction being in the central axis direction.

A vehicle shifter assembly having a housing rotatably supporting a monostable toggle knob accessible to a vehicle operator. A processor enabled printed circuit board is incorporated into the housing and, upon actuation of the knob, instructs a gear shift condition to a display component. The housing can be incorporated into any of a variety of locations accessible to the vehicle operator, including being integrated into the steering wheel so that, and upon rotation of the wheel, the housing or display is continuously reoriented so as to maintain an upright position as viewed by the operator.
