HZ910‑10P/3 is a marine‑grade rotary combined change‑over switch, upgraded version based on HZ10D‑10P/3 land‑type switch.

Designed for manual non‑frequent circuit switching onboard vessels.

It can connect, disconnect and switch resistive‑inductive mixed‑load circuits.

It is also capable of controlling small‑capacity AC motors, lighting circuits and power distribution loops in marine control cabinets.

This model features 3‑layer structure with 9 terminals, built to withstand harsh marine working conditions including vibration, humidity and salt mist.

Key Features & Quality Advantages
Adopts high‑purity copper contact components, low contact resistance, stable conductive performance and low heat generation.
High‑strength anti‑aging insulating base, good dielectric property, resistant to humidity and salt fog corrosion for marine environment.
Spring‑energy‑storage operating mechanism ensures reliable make‑and‑break action independent of manual rotating speed, greatly improving electrical breaking performance.
Excellent anti‑vibration and shock‑resistant capability, suitable for vessel swaying and bumping conditions.
Compact panel‑mount structure, easy for installation and wiring; clear rotary handle for simple manual operation.
Strict factory inspection before delivery, stable electrical and mechanical service life.
HZ910 series is specially optimized for marine use compared with ordinary land‑type HZ10D series switches.
