Rule 3-Way Bilge Pump Panel Switch, it comes with a panel and will make a neat, tidy installation in your vessel. Manual position has Rule's "fail-safe" spring return to 'OFF'. Works with any voltage. Plate size is 2-1/4" x 2".
The mini accumulator tank smoothes water flow and reduces on/off switch cycling of the pump by lessening the variation in pressure and flow between the pump and the system discharge points. The even flow of water gives better control of hot water temperature with systems using instant water heaters. Its compact design also allows for convenient installation in tight spaces.
