Sealed Electromechanical Contactor Solenoid Switch
Description
This sealed electromechanical contactor switch is a direct, high-reliability replacement for the motor-reversing solenoid in PIERCE PSW654-8K, PSW654-8MK, PSW654-11K, and PSW654-11MK winches (9,000–12,500 lb. capacity). Built for demanding recovery, industrial, and off-road use, it provides dependable forward/reverse polarity control with sealing against dust, water, and harsh environments.
Key benefits include:
- IP67-rated sealed construction for superior protection in wet, muddy, or dusty conditions
- High-current handling for winch inrush demands during intermittent pulls
- Weld-resistant silver-alloy contacts and magnetic arc suppression for long service life
- Easy mounting with pre-fitted bracket and large terminals for secure connections
Ideal for maintenance or upgrades—keeps your PIERCE winch performing reliably with minimal downtime. Professional installation recommended; refer to your PSW654 manual for wiring.
