Carl & Gilberts 20 A Neon Water Heater Switch is a heavy‑duty wall switch designed to control electric water heaters or other high‑current appliances safely. It features a 20‑amp double‑pole design, which means it isolates both live and neutral circuits — a useful safety measure for water heaters. The built‑in neon indicator light illuminates when the switch is ON, giving a clear visual signal that the water heater is energized. With its robust plastic housing and standard sized plate, it’s built for easy flush‑mount installation and long‑term reliability. This switch offers a simple, practical solution to add controlled power supply to a water heater, enhancing safety and convenience.
