Why to some of these have float switches while others do not? What are the differences / advantages?

Free Float gives you more range for the on and off settings (good if you have water coming in steady). The downside is it requires more room than floats mounted directly on the pump.

It really depends on the purpose you want the pump for. Sump pumps are often coupled with the float switch, so that whenever the water level rises to a certain level the pump turns on to purge the sump. If you want to control when the pump runs, emptying ponds, pools, etc, then you wouldn't need the float switch.

Pumps do not like to run "dry". The float switch turns off the pump when the water level drops below the suction inlet to protect the pump from burning out. I have burnt out many a pump that did not have low water switches.

We currently only have the ones in the first photo (with multiple notches), however, both ballasts are functionally identical. The one with multiple notices has better cooling capabilities because those notches are heatsink fins intended to cool off the MOSFETs inside the ballast. Hope this helps!

Doesn't really matter with a spst switch. If you you are using with a circuit that it matters such as led I usually put it in the positive power supply leg.

I am not an electrician. I spoke to the Lutron team. They told me that switches will differ slightly in looks and functionality from one subtype to another. The main difference here is the appearance- paddle switch Vs flat switch. The best way is to call Lutron Customer Service. They are very responsive and informative.

It's a float, but may hold a small amount of sand to create the proper up and down motion to activate the switch.

Kathy, Very good question. I don't see what the purpose of the float is - it does not connect to anything, not a level gauge, not a shut-off switch, nothing. The best I could figure was using the one screw to attach the white part to the one pre-drilled screw hole.

Not sure. What i can tell you is one switch is a dimmer (analog slide) and the other is a three position switch (clicks in 3 positions).

I think the only difference is the labeling of the keys. I use a Windows keyboard for my Windows 7 computer so never tried to switch them.

This switch isn't really meant for continuous power. So it wouldn't stay 'on' as long as the float is in a particular position.Basically, when the float 'triggers' the switch to run (ie power on), it is programmed to automatically run for about 10 seconds, then it shuts off the power again.This time limit is hard coded and not configurable either.I don't think it will work for what you want to use it for.

My experience is that the DIP SWITCHES are upside down. Try reversing what you are doing.

No, it does not use 'real' switches as the old IBM clickers did.Still, I feel it does have superior-to-many membrane construction.

The actual float does not slide much up and down the stainless shaft. The float has limited movement due to two snap rings spaced about 1.5" apart. The float measures 1.1" so tripping occurs within 0.4" of its pictured location. In reality, tripping probably occurs within a 0.25" to 0.375" of the end stop ring. One thing not clearly understood from the description is that the device uses a very high reliability reed switch contained within the stainless shaft. Reed switches are activated by an external magnet that, in this case, is contained within the float. My long term concern for this part is the "E" clips seem to be made from plated steel and may rust over time. The rest of the device probably will have extremely long life provided the reed switch contact ratings are not taxed. However, if the liquid being sensed has a lot of contaminates, then a possible buildup of contaminates might occur between the shaft and the float's hollow opening. Some periodic cleaning maintenance might be needed based on the application. The jury is still out on my usage but the device is working very well.

I don't know what you mean by double switch, but I can tell you that this pump has the electrical cord that you plugged in the outlet and a float switch by the pump it self. When water reaches the hi level the ball float switch turns on the pump.

Mine has dual switches, but honestly I can't figure out what the one does... It is a very nice product though.

I did not use this float switch in a tank. I set it up on a sump pump to keep water out of my well pit. It works great for that purpose. It is used more for turning on the pump when water is high. And emptying rather than filling to a set level.

I have no experience using the X10 switches but what little I read about them and using them with LED and other lighting, they may not work so well. LED lights are not generally designed to be used in alternative switched use.

The switches are not polarized. Think of them as a piece of wire that is continuous when the button is pressed. You can connect them with either terminal to either pole of your voltage source.
