Auto-Stop System Compatibility
The KALS Limit Switch is a key part of auto-stop systems, which allow you to raise or lower your lift to specific preset positions with a single press of a button. Without a limit switch, the lift must be manually stopped.
Auto-stop systems are ideal for convenience and safety — ensuring consistent lift positioning and preventing over-travel or equipment strain.
The GEM KALS Limit Switch for BH-USA A-Drive provides reliable, automatic lift control and protection for your boat lift system. With factory-wired precision and seamless integration with GEM Remotes, it’s the perfect solution for upgrading or replacing your A-Drive’s auto-stop system.
