BH-USA KRLS GEM Boat Lift Remote Limit Switch
This limit switch is pre-wired for Auto Stop and counts rotations of the hoist pipe. It is designed to work with GR1A and GR2A remotes, making it a strong choice for Gem remote users who want a straightforward, plug-and-play solution.
Best for: Gem remote users needing easy auto-stop integration.
Why selected: Simple setup, reliable rotation-counting, and compatibility with common Gem remotes.
Limitation: May require matching remotes and mounting to ensure optimal counting accuracy in certain installations.
BH-USA KFLS GEM Boat Lift Remote Limit Switch
This switch counts the rotation of the gear and fits the front of a flat-plate hoist with a special bracket included. It works with grab and gr2a remotes, giving flexible control for GEM systems that require precise front-mount sensing.
Best for: Front-mount installations and GEM remote users who need gear-rotation sensing.
Why selected: Bracketed front-fit design, compatible with multiple BH-USA remotes.
Limitation: Front-mit mounting may require exact alignment with your hoist profile.
Rotary Limit Switch for GR2A or Tec II Remote
Designed to complete the auto-stop feature for Gem 2 Motor Remotes, this rotary switch helps ensure precise stop points when used with GR2A or Tec II systems.
Best for: Gem 2 Motor Remote users seeking a dedicated auto-stop completion switch.
Why chosen: Supports auto-stop completion with GR2A/Tec II remotes.
Limitation: May require correct alignment with the Gem 2 motor setup for accurate rotation counting.
AMS Boat Lift Switch – DOCK SOLUTIONS
This 3-position switch uses a spring-return mechanism and is rated for up to 2-HP motors. It features corrosion-resistant stainless steel terminals for enhanced durability in harsh marine environments and a compact, protected enclosure.
Best for: Coastal or saltwater setups needing durable, corrosion-resistant construction.
Why chosen: Stainless terminals and sealed housing improve longevity in challenging conditions.
Limitation: Spring-return action means it returns to center after actuation, which may not suit all control logic without additional wiring considerations.
BAOMAIN WLCA12-2-Q Adjustable Roller Lever Limit Switch
This adjustable limit switch features a 180-degree rotary lever with an adjustable length and a smooth steel roller, ensuring precise actuation. It is IP66 waterproof and supports up to 380V AC / 220V DC with a 10A rating and SPDT (1NO 1NC) configuration.
Best for: Industrial or heavy-duty setups needing precise actuation and durability.
Why chosen: Highly adjustable with robust protection, suitable for varied mechanical arrangements.
Limitation: Installation may require careful mounting to maintain consistent actuation points across cycles.
Buying Guide
Key considerations to help you pick the right boat lift limit switch:
- Ensure the switch works with your hoist model (Gem GR1A/GR2A, Tec II, or other remote systems) and mounting hardware.
- Choose between rotation counters, lever arms, or SPDT configurations based on your mechanical setup and circuit logic.
- For saltwater or coastal use, prioritize IP66/IP67-rated enclosures and corrosion-resistant terminals.
- Verify voltage and current handling (e.g., 10A, 15A, up to 380V) to match your control circuits and motor requirements.
- Look for stainless steel components, sealed housings, and gasketed designs to resist dust, water, and oil exposure.
- Consider mounting space and whether the switch needs to be front-mounted, inline, or remote-actuated for easy access and maintenance.
- Some units have spring-return or self-locking features; confirm how these affect long-term operation and safety interlocks.
Frequently Asked Questions
- What is a boat lift limit switch used for? It detects end points or positions to automate stopping of a boating lift and prevent over-travel.
- Do I need IP-rated switches for marine environments? Yes. IP66/IP67-rated switches protect against water, dust, and moisture in harsh saltwater conditions.
- Can I mix limit switches with different remotes? Compatibility depends on the remote system and mounting; verify with each product’s stated compatibility.
- Is a rotation counter necessary for all boat lifts? Not always; it depends on whether your system requires precise rotation-based stopping or simple end-stop sensing.
- What maintenance is recommended for boat lift switches? Regular inspection of seals, terminals, and mounting tightness helps ensure reliable operation in marine environments.
- How do I choose between IP66 and IP67 switches? IP66 is dust-tight with water jets, while IP67 tolerates immersion; choose based on exposure risk and water exposure level.
