Which component stops power to the winch motor when the davit arm trips the switch?

When a davit and winch reach their end of travel, a device built to sense that position is triggered to stop the motor. That device is a limit switch. It is arranged to be actuated by the davit arm at the limit point, and when activated it breaks the electrical path powering the winch motor (or signals the controller to stop the motor). This provides an automatic, immediate shutoff to prevent over-travel, equipment damage, or unsafe conditions. General switches wouldn’t automatically stop at the limit unless wired into the control logic, and circuit breakers protect against electrical faults (overload/short) rather than stopping at a travel limit. Relays can control power to the motor but are not the mechanism that inherently stops motion at the end of travel. The limit switch is specifically designed to detect the arm’s travel limit and interrupt power to the motor.
