The Powermaster Dual Immersion Switch typically features two separate switches, allowing for independent control of two immersion heaters, while the neon indicator light provides a visual indication of when the switch is turned on. The switch is designed to handle the high current demands of an immersion heater, and it has a maximum current rating of 20-30 amps. The Dual Immersion Switch with Neon is commonly used in residential and commercial settings, particularly in properties with a high demand for hot water. It is often used in properties with multiple bathrooms or in areas where hot water is in high demand. The neon light provides a clear indication that the switch is on, which can help to prevent accidental activation or left-on scenarios.
