In modern ship control systems, the main propulsion control lever serves as a critical human-machine interface device that precisely transfers steering commands to the propulsion system.
By pushing, pulling, or adjusting the angle of the lever, the operator sends speed and direction signals to the control system, which then drives the main engine or thruster accordingly. The lever's control linearity, centering accuracy, redundant signal output capability, and long-term reliability under harsh environmental conditions such as vibration, salt spray, and t...
