Heavyduty momentary polarityreversing switch built for motorized RV and trailer systems Key benefits Durable construction for reliable performance: Built to withstand tough conditions so your switch keeps working reliably in marine, road, and outdoor environments. Safer, simpler operation: The momentary automaticreset function only powers the motor while you press the control, reducing the risk of unintended continuous operation. Fast motor direction changes: The polarityreversing feature lets you change motor direction quickly and easily — ideal for reversing winches, jacks, and other DC motors. Tool mounting option: Includes an aluminum plate labeled UP/DOWN and matching screws so you can install the switch cleanly without drilling. What this switch does for you Solves control and safety problems: Momentary automatic reset prevents motors from running unattended, reducing wear and potential damage. The polarity reversing function eliminates the need to rewire or swap connectors to change direction. Saves time during installation and maintenance: The labeled aluminum plate and supplied screws simplify mounting and wiring, letting you get systems operational with minimal effort. Stands up to realworld use: Heavyduty materials and construction mean fewer failures and less downtime in demanding applications. Compatibility and materials Function: Momentary (automaticreset) polarityreversing switch for DC motor control. Material highlight: Durable aluminum mounting plate labeled UP and DOWN for clear orientation; robust switch construction to endure rugged use. Typical compatibility: Designed for use with RV and trailer motorized systems and other similar DC motor applications. Practical use scenarios RV leveling jacks: Quickly reverse jack motors to raise or lower without worrying about accidental continuous operation. Trailer winches: Control winch direction during loading and unloading with a momentary switch that resets automatically when released. Motorized slideouts or doors: Reverse motor direction for extension and retraction while keeping operation momentary and controlled.
