DaierTek Waterproof DPDT Reverse Polarity Switch 12V – Momentary On-Off-On, 30A DC (RV/Motor Control)

Meet a rugged solution for DC motor control with the DaierTek Waterproof DPDT Reverse Polarity Switch. Designed for 12V systems, it provides a three position layout—ON, OFF, and a second ON position to reverse polarity—so you can fine tune motor direction without rewiring. The device brings tactile feedback and durable construction to environments that demand reliability, from RV setups to workshop benches. Its waterproof seal and rubber cover help protect the contacts from moisture and dust, making it suitable for outdoor use and travel where splashes and vibrations are common.

Built to endure, the switch uses a black rubber covered body for moisture resistance while maintaining a straightforward wiring experience. Two 14 AWG leads simplify connections, and a compact 12 mm cut-out enables a neat, low-profile install. The 4-pin wired configuration supports efficient control logic for motor drivers, power jacks, or simple line switching in compact setups. Whether you are updating an existing RV power jack or integrating into a custom DC motor project, this switch keeps the wiring tidy and dependable.
