The invention relates generally to portable internal combustion engine powered devices. Public a small engine control combination switch comprising a knob assembly, a bracket and a choke cable, knob assembly includes a fixed plate, characterized in that the fixed plate with a rail; the bracket including a first hole. The choke cable connects with the rail through the first hole. The height of the rail is gradually increased, rail pivot drives the choke cable on the top of the track moves up and down; also further includes a fuel switch, a fixed plate is provided with a rotating shaft, the shaft connecting the fuel switch. The invention through the choke point of engine control, start-up, operation and shut down control, which simplifies the traditional steps of engines, generators and other equipment, greatly simplifying the operation process, improving the operation efficiency.

[Problem] To provide an actuator control device with which desired drive control characteristics can be obtained by means of a simple operation.

[Solution] This device performs: a reception process (S12) in which designations of a minimum operation amount and maximum operation amount of an operation unit for driving an actuator, and a maximum driving speed which is the actuator driving speed corresponding to the maximum operation amount are received; a determination process (S13, 14) in which a function representing a characteristic line that links a first point, which corresponds to the minimum operation amount and the driving speed of 0, and a second point, which corresponds to the maximum operation amount and the maximum driving speed, is stored in a storage unit as a drive control characteristic; and a drive control process in which, in response to operation of the operation unit, the actuator is driven at a driving speed corresponding to the operation amount specified by the drive control characteristic stored in the storage unit.

A base frame assembly and a chair are disclosed. The base frame assembly includes a frame body, a lifting connecting structure, a translation connecting structure, a backrest connecting structure and a control handle. The lifting connecting structure is used for driving the frame body to lift up or down. The translation connecting structure is used for driving the frame body to move back and forth and/or move left and right. The backrest connecting structure is used for driving a backrest to rotate relative to the frame body. The control handle is movable and/or rotatable in at least three different directions, to respectively drive the lifting connecting structure, the translation connecting structure and the backrest connecting structure through different motion trajectories.
