QWORK 12V 250A Winch Solenoid Contactor with Rocker Thumb Switch — Black, Weather-Resistant

QWORK 12V 250A winch solenoid relay contactor with rocker thumb switch kit is a direct-replacement electrical switch assembly designed to operate ATV/UTV winches rated roughly 2000–5000 pounds.

This compact kit combines a heavy-duty 250A solenoid contactor built from weather-resistant steel and a thumb-operated rocker switch so you can reliably control your winch from the handlebars. It’s designed to replace worn or damaged winch solenoid valves and includes protective caps and the necessary wiring points to integrate with common 12V ATV/UTV winch systems.

How does this relay contactor improve my winch’s performance?

The QWORK 250A contactor provides a consistent electrical path for winches, reducing voltage drop and ensuring reliable engagement under load. Its powder-coated steel body resists corrosion and physical wear, helping maintain performance in harsh outdoor conditions.

• 250A current capacity supports mid-range winch loads without overheating.
• Black powder coating shields the housing from rust and abrasion.
• Direct replacement form factor simplifies swap-in installation.
• Includes six protective caps to keep terminals clean and dry.

What’s included and how do I connect the thumb switch?

The package bundles the solenoid relay contactor, a rocker-style thumb switch with black and green wires, and protective caps for exposed terminals. Installation requires attaching the black and green wires on the switch to the matching solenoid wires and securing power and load leads to the contactor’s terminals.

• Rocker thumb switch with pre-wired black and green leads for quick hookup.
• Contactor terminals labeled for battery and winch leads to avoid confusion.
• Six protective caps to cover unused or exposed posts after wiring.
• Hardware-friendly layout for common ATV/UTV mounting points.

Is this contactor compatible with my winch and vehicle?

This QWORK solenoid contactor is specified for 12V systems and rated at 250 amps, making it suitable for many ATV and UTV winches in the approximate 1500–5000 lb range. Always confirm your winch’s voltage and current requirements and compare terminal layouts before replacing the existing solenoid.

• 12V system compatibility—standard for most small-vehicle winches.
• 250A rating matches mid-range winch draws under load.
• Intended as a direct replacement for similarly sized contactors.
• Check terminal spacing and mounting points against your original part.

How do I maintain the solenoid and extend its service life?

Routine inspection and protecting electrical connections are the simplest steps to keep the contactor working reliably. Use the included protective caps, tighten terminal fasteners to proper torque, and keep the assembly free of mud and moisture to prevent corrosion and electrical resistance.

• Use protective caps on all exposed posts when not in use.
• Periodically clean terminals and check for tight connections.
• Inspect switch wiring for chafing; secure with cable ties if needed.
• Avoid submerging the contactor; mount in a sheltered location if possible.

Who is this for: The QWORK 12V 250A winch solenoid relay contactor kit is aimed at ATV and UTV owners, mechanics, and outdoor enthusiasts who need a robust replacement solenoid for mid-range winches. It’s useful for anyone replacing a failed relay, upgrading a worn switch assembly, or building a reliable control setup for trail, utility, or recovery tasks where a dependable electrical contactor and a convenient thumb-operated rocker switch are required.
