Stellar Industries 42821 12V Winch Contactor – Warn DC2000 / DC2500

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar Industries 42821 12V Winch Contactor is an heavy-duty solenoid switch designed for controlling the power and directional rotation (forward/reverse) of Warn DC2000 and DC2500 electric winches. Engineered for harsh commercial environments, this 12-volt DC contactor handles high current loads during heavy winching operations while protecting the electrical system against premature arc wear and electrical failure.

Featuring a sealed, rugged housing, this direct-fit replacement contactor ensures reliable power distribution from the vehicle battery to the winch motor, restoring smooth, responsive control to your service truck or utility crane setup.

What This Part Is Used For

The Stellar 42821 contactor routes high-amperage 12V DC battery power to the winch motor based on signals from the remote pendant or switch control. It safely toggles the electric motor between power-in, power-out, and off positions during load-hoisting operations.
