HOW DO YOU WIRE TO PUMP, ANDCAN YOU USE EXISTING PUMP OR DOES IT HAVE TO BE A RULE PUMP?

Asked on 05/09/2012 by mark baumgardner

Top Answer

This float switch can control any 12V DC bilge pump up to 14 amps. Rule offers a larger switch for pumps requiring over 14 amps. I suggest using the Rule bilge pump panel switch in combination with the float switch for complete user control. Wiring diagrams are provided. The installation is not difficult, but basic electrical knowlege is necessary for safety. Hope this helps. Salty Dawg

Answer

I use them on many types of small DC-powered pumps, not just Rule. They install very easily: I put the switch in series with the positive voltage feed from the battery or bilge pump switch. It can be as simple as just cutting the hot wire to the pump and putting the switch in series- one leg from the switch to the hot side, and one leg to the pump side. Make sure that the connections are well supported in a place that will keep them up out of any water in the bilge (I use a ty-rap to hold them up to some structure in the area). As a further waterproofing measure, I always use some form of watertight connectors. The ones I prefer are crimp connectors that then heatshrink firmly to the wire using a heat gun. For small bilge pumps, this works very well. For larger, high-current pumps that draw more than just a couple of amps, you'll need to use a relay controlled by the switch to handle the high current load.

Answer

You can use any pump as long as the current draw is less than the rating for the Rule Switch. Wire it in series with one of the pump power leads so that the float switch will provide power to the pump when it is raised by the water level. Then when the pump removes the water the float switch will lower and turn off the pump.

Answer

For sure use your existing pump- I think you need to have the Amp rating match- which they inevidently probably do. The wiring is -- no problem- Just insert the Switch into the 'circuit' with the Pump. Each has two wires. Connect One of the wire from Pump to One of the wires of the switch. I use a 'heat shrinked' connector. Leaving One wire 'free' from the swith and one wire free' from the Pump- these go to your Plus and Minus power source. As you can see I am an 'idiot-savant' electrician- but it worked OK for me

Mark: Be sure to keep your wire connections outside of the water.

Question

Can this switch be used for a 6 volt DC pump?

Top Answer

Rule states the voltage range for this specific switch is 12/24/32 VDC. I realize that voltage maximum is usually more of a factor, you may want to contact Rule directly. It may also be dependent on the wire gauge they use for the float switch, as it would probably need a thicker gauge is my guess.

Can anyone tell me at what level the switch activates and deactivates? Others I've seen activate at 2" and deactivate at 3/4" but not sure if this one does as well.
