Float switch varieties

[Spider_Whistle]

switch one (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2315330636&category=20755)

switch two (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=20758&item=2315330959)


Is there really any reason I should spend $10 more for the second one? Besides its easy setup and suction cup, does it really offer anything special?

Sorry, this is probably a pretty stupid question, but I've never used a float switch, so I had to ask ;)

Thanks

Depends on how much DIY you want. Float switches are easy to wire, but if you want one that's ready to use - spend the $10 extra.

Personally, I think the 2nd one is pretty cool idea. It's a clean setup and its RTU. Easily worth $10 more in additional parts & labor. It could be used for a solenoid on an RO unit or freshwater bucket as well.

I'm actually using that exact float switch right now. It was very easy to install, just use a very small pump that uses low wattage so you don't burn up the switch itself.

I had a different float switch, and decided to test it to see how it worked. Instead of plugging in a lamp or a radio, I thought a hair dryer would be a good indicator of it cycling on and off. Turns out 1500w destroys the float sensor instantly. So I ordered 2 of the #1 above, which I received within a matter of days. Works great.

Either switch will work, but if you put too large a pump on it you will burn the contacts out on the switch. If you use anything larger than a powerhead you will need to wire up a relay in the system. There is a diagram in the DIY forum showing you how to do it w/ using the same switch.
