The limit switch should stop power to the winch motor when the davit arm trips the switch ___ from the stops.

The main idea is to stop the winch at a safe, controlled distance from the physical stops so the load settles without slamming into the stops. The limit switch is wired to trip when the davit arm is about 12 inches from the stops, giving enough deceleration time for the winch and reducing shock on the cable, drum, and gears. This distance lets the arm reach a near-final, stable position without actually contacting the stops. If the switch activated closer (6 inches), the stop could be too abrupt and there’s a higher risk of impact or wear. If it activated farther away (24 or 36 inches), the arm would stop well before reaching the intended position, preventing proper seating against the stops and potentially causing misalignment or wasted motion. So, 12 inches provides a safe, smooth, and reliable stop.
