The switch can be used for that but only to activate a contractor, the switch is not rated for vary many amps,second use a reduction tee. 2x2x1/2. Or so on ,you trim off the excess on the paddle, also 1x1x1/2. Tee ,recommend on the output side of the pump **Q: What is the electrical rating, volts and amps?** A: The model I bought was rated at 120VAC 0.5A or 24VDC 1.5A **Q: This switch is rated to actuate at 2.6gpm water in horizontal flow. Any data what the trigger rate would be in downward cold water stream?** A: The flow switch is counter balanced to move with gravity assist. I don't believe it will work in a downward flow direction. Horizontal or up flow. **Q: Defective unit? Stays Closed regardless of paddle position. Even disconnecting the wire from the switch body, current still flows.** A: Must be defective. Purchased many and all work. Switch closes when flow moves paddle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***K on 6 January 2020* This is a good quality flow switch. Works well. Installs easily.
